That this House has considered Sudden Unexplained Death in Childhood.
It is a pleasure to serve under your chairship, Sir John, and to open this important debate. Today we are discussing a category of child death that has previously been described in this room as
“one of the most serious medical phenomena in our country”.—[Official Report, 17 January 2023; Vol. 726, c. 88WH.]
Sudden unexplained death in childhood is the fourth leading cause of death in children aged one to 18. Since Parliament last debated this issue in 2023, in the UK around 120 children who appeared perfectly healthy have died suddenly. That is the equivalent of four full classrooms of pre-school and school-aged children—four classrooms of lives cut short without explanation.
For families, the devastation after a child dies is immediate and lifelong. What makes SUDC uniquely cruel is not only the loss, but the absence of answers. Why did those children die? I can only imagine the pain of that. When we lost our daughter Mallorie to Edwards’ syndrome, we at least had the comfort of knowing why and what was coming. We knew there was nothing more we could do. Families experiencing SUDC have none of that. It is brutal. We cannot continue to tell grieving parents, “I am sorry; we simply don’t know why your child died.” As a society we have a responsibility to do all we can to find the answers to prevent future deaths. That is why today we ask the Government to lead the search for answers through a co-ordinated national plan.
First, let us be clear about what SUDC is and what it is not. Sudden unexplained death in childhood is the sudden unexpected death of a child over one year old that remains unexplained after a full investigation. Cases do not involve crime, terminal illness, diagnosed epilepsy, cardiac conditions or tragic accidents. The children appear healthy. They fall suddenly ill or go to sleep and never wake up. Parents, grandparents and siblings are left asking, “Why did this happen? Could it happen again? Is there a genetic risk? Will my other children die? Should we risk another pregnancy?” Those are questions that currently no one can answer.
At the heart of today’s debate and our discussion is a little boy named Frankie Grogan. Frankie was three years old: bright, curious and full of energy with a particular love of giraffes. His family had every reason to believe that they would watch him grow and thrive. Instead, he went to sleep and did not wake up. The night before, Frankie was excited that his father would be running the Manchester 10k the next day. He briefly woke at 4.30 am asking for water. A few hours later, he was found to be still and unresponsive. Despite a thorough investigation, no cause of death could be identified. That happened in 2019 and Frankie’s family, who are here today, still do not know why.
In the midst of unimaginable grief, Frankie’s grandfather, Brian Topping, came to see me. He did not ask for sympathy; he asked for structure, leadership, co-ordination and a plan. Frankie’s story reminds us that behind every statistic is a child with a name, a personality and a future that should have been. It is because of Frankie and the determination of his family that the debate is taking place today. Through SUDC UK, families, clinicians and researchers have united around the conviction that unexplained should never mean unexamined. We know that research and awareness raising, backed up by national leadership, can make a profound difference. In other areas of childhood death, when priorities are clear, progress follows.
I thank the hon. Gentleman for bringing forward this important debate and for his very moving speech. I recently had the honour of meeting Eleanor Wroath, who is here in the Gallery today with her son Sam. Eleanor lost her daughter Miranda, aged 18 months, in 2008. Since then, she has been a tireless campaigner for raising awareness of sudden unexplained death in childhood. She and Sam will be running the Great North Run in support of the charity. Does the hon. Gentleman agree that, as highlighted by campaigners such as Eleanor and Sam, there is an urgent need for more specialist research to understand the causes of and the risk factors underlying SUDC?
Order. Given the seriousness of the subject and of the hon. Lady’s intervention, I let that go, but interventions should generally be slightly more pithy.
Yes, of course I agree, and I am coming on to the research. We simply owe families answers and our best efforts to find those answers.
As I was saying, we know that research and awareness raising, backed up by national leadership, can make a profound difference, as it has in other areas. When priorities are clear, progress does follow. For example, research and safer sleep campaigns have significantly reduced unexplained infant deaths—known as sudden infant death syndrome, formerly cot death. About 200 babies die from SIDS each year compared with 40 older children from SUDC, yet there has been 100 times more research into SIDS than SUDC, which receives only a fraction of the attention.
Peter Fleming CBE, the clinical lead for the SIDS Back to Sleep campaign and a scientific adviser to SUDC UK, has said:
“Research into unexpected deaths in infancy has led to an 80% reduction in such deaths over the past 30 years in the UK. Unexpected deaths in older children are less common, much less well understood, and to date little research has been conducted in the UK to try to understand or prevent such deaths… I am convinced that with the right research we will soon be able to prevent many deaths”
of older children. The families here today are not asking for guarantees—they understand that science takes time—but simply asking for this issue to be treated with the urgency it deserves.
I congratulate the hon. Member on securing this debate on what is an incredibly emotional topic. It is difficult to imagine parents having grief beyond what he is describing. On the research, does he agree that while no guarantees can be given, if Governments put more money into it, families will understand that and will see progress and, we hope, a better outcome?
Precisely, and that would be to treat this issue with the importance, urgency and focus that it deserves. The very fact that most research is now charity-led is quite revealing.
This research includes the Pioneer study—a population-based investigation to reduce sudden unexplained deaths in childhood—at the University of Bristol, which is beginning to analyse national mortality data and incorporate family-led research priorities. Science has advanced: genomics, cardiology, neuropathology and data science now offer real hope that the causes that were once thought unknowable may finally be within reach. However, scientific possibility alone is not enough. Findings from the UK’s Pioneer study, alongside the growing body of global evidence on SUDC, must be properly considered and applied. They should inform linked datasets and guide action by organisations such as Genomics England, the National Institute for Health and Care Excellence, the National Institute for Health and Care Research, the Department of Health and Social Care and the NHS.
The opportunity is there, but right now we rely far too much on this limited charity-funded research. If we are ever to shift the dial, as the hon. Member for East Londonderry (Mr Campbell) said, we need a national plan delivering co-ordinated, planned actions that enable and accelerate meaningful projects.
I thank my hon. Friend for bringing forward such an important debate. Constituents of mine have asked me to attend not just to thank him, but to support his calls for a co-ordinated strategy. They lost their son when he was three, so they share all such families’ feelings that more needs to be done to get to the bottom of understanding the unimaginable tragedy that many parents have suffered, so there is a bit more closure.
I thank my hon. Friend for that intervention, which again focuses on the need for co-ordination in the effort to meet the scale of this challenge.
One of the most compelling issues requiring investigation is the association between SUDC and febrile seizures. National and international data show that 30% of SUDC cases involve a history of febrile seizures—10 times higher than in the general population. Frankie Grogan had 12 seizures before he died, but he was never reviewed by a specialist. At this point, it is really important to stress that febrile seizures are very common and SUDC is rare, but the persistence of this correlation—known before the last debate—demands investigation. A national plan must accelerate understanding of the link and determine whether children who have repeated febrile seizures, or a particular subset of affected children, need different pathways of care.
We must also improve public information. Information for families is inconsistent and, at times, invisible. Leaflets on febrile seizures vary significantly across NHS trusts; some fail to mention that seizures can occur during sleep or that monitoring options exist. SUDC itself—including the 60% of cases with no seizure history—is missing from the NHS website. After the 2023 debate, a token reference was added to the SIDS page, but then removed. Imagine a family receiving a post-mortem conclusion of SUDC but finding nothing when they search the NHS website. That is clearly unacceptable, but something that the Government can easily fix.
There has been welcome progress in other areas. The national child mortality database is a world-leading resource. Since the previous debate, the NCMD has created SUDC-specific forms and launched pathways for genomics and cardiac screening. SUDC UK, a charity founded only in 2017, has helped to ensure that families have access to whole genome sequencing through the R441 pathway. That advocacy was born out of what Nikki Speed, chief executive of SUDC UK, describes as the “paralysing fear” that she and many families carry every day. She explained to me that for years after her loss, she got little sleep, because she was constantly having to have a hand on her surviving children to be sure they were alive and well.
The hon. Member is certainly making a very powerful speech on this issue. On 7 January 2024, Teddy Jason Williamson, aged just seven weeks and from my constituency, died of sudden infant death syndrome. Does the hon. Member agree that more practical support is required? Yes, we need research, but we also need there to be practical support: bereavement nurses, dedicated suites in hospitals, and counselling support post the death of the child.
Yes. I will touch on that in a moment. It is part of a wider picture of bereavement support and bereavement pathways nationally. From baby or infant loss to unexplained death in childhood, bereavement services are patchy and in many cases far below the standards that we need to see. We need to make that service universal.
Let us move on to another cause of trauma: child death investigations. This issue is wider than SUDC but has profound impacts. Current national guidelines—the statutory guidance and joint agency guidelines—are built on historical evidence from infant deaths and have not been updated since the new pathways for genetics and cardiology were launched. That is important as it may affect inequity of care and access to these important tests. Guidelines should be updated to reflect new evidence and current pathology timeframes, and any consultation on those updates should include charities such as SUDC UK, which supports families of children up to 18 years old.
From investigation to family support, NCMD data tells us that 30% of all child deaths are sudden and unexpected, and a fifth of families leave A&E with no understanding of why their child has died. While consistency has improved since the last debate, the quality of bereavement support remains deeply uneven, as the hon. Member for Upper Bann (Carla Lockhart) has raised. Families affected by SUDC often experience complicated grief with severe and long-lasting consequences for parents and siblings, and this requires specialist support. The NIHR-funded Quintet project and the wider strategic partnership for sudden child death will soon provide evidence-based recommendations for supporting those families. These should be incorporated into a national plan.
To conclude, what is lacking is not expertise nor compassion; rather, it is co-ordination and leadership. I am calling for a Government-led national plan for sudden unexplained death in childhood. That would turn the issues that I have raised into strategic objectives with clear timelines, milestones and measurable outcomes. It should be developed alongside families, clinicians and researchers, and report back to Parliament every two years. Such a plan would send a powerful message: these children matter, their deaths are not footnotes, and unexplained does not mean unimportant. My thanks to Brian Topping, Nikki Speed, the courageous families here today and all those who have worked tirelessly for progress and understanding. I hope that this debate can play a part in delivering that.
I remind Members to bob—and I can see that they are doing so. A number have indicated that they desire to speak. Given the seriousness and sensitivity of the subject, I want to be able to get them all in. Please bear that in mind when you contribute.
It is a pleasure to serve under your chairmanship, Sir John. I thank the hon. Member for Rossendale and Darwen (Andy MacNae) for securing this really important debate.
There are a few meetings that Members of Parliament never forget. Over three years ago, in January 2023, I met my constituents Cheryl and Darren Midgley for the first time. On Christmas day 2022, Cheryl and Darren put their loving, happy and healthy 16-month-old son Jack to bed. The family had enjoyed the best Christmas, but when Darren, the father, went into Jack’s room the following morning, he quickly realised he had gone. He said that, that day, their “world fell apart”.
Christmas in the Midgley household is never just a day. Jack, with his brother Louis, saw Santa four times. They had had the best Christmas. On Boxing day, when Darren cracked open Jack’s door and went into the room, he said there was perfect silence. He walked over to his son’s cot, but as soon as Darren put his hand on his back, it was cool. From what Darren saw at that point, he knew that his baby son Jack had gone.
Jack was taken to Martin House children’s hospice in Wetherby, where he was cared for in one of its special cooled bedrooms. Darren described the hospice’s services as an anchor for the family. The fact that Jack could stay in one of the cooled bedrooms meant the world. Darren said:
“It was a huge comfort to us to know Jack was being looked after in a bedroom, in his Christmas pyjamas, and the staff would be there to talk to him and put his night light on.”
The family spent five days at Martin House until the post-mortem could take place, but the results were inconclusive.
Since meeting Cheryl and Darren three years ago, I have kept in touch with them, and I have been truly blown away by their resilience and mental fortitude, as well as that of their eldest son Louis. They have worked tirelessly to raise awareness to help others, despite their own grief, including by completing a 127-mile bike ride along the Leeds to Liverpool canal path, raising over £6,000 for the Airedale Hospital & Community Charity, where Cheryl works as a nurse.
It is a pleasure to serve under your chairship, Sir John.
The death of a child is something that no parent should ever have to endure. It is every parent’s worst nightmare. There are no words that can make sense of it, and no pain more unimaginable. For many families, understanding why their child died is an important part of beginning to process their grief. It does not take the pain away, but it can bring some sense of clarity. For families affected by sudden unexplained death in childhood, the answers never come, and that absence—that not knowing; that lack of clarity—brings its own trauma.
SUDC is the sudden and unexpected death of a child between the ages of one and 18, where no cause can be found, even after investigation. It is one of the leading categories of death for children aged one to four in England and Wales. Yet despite that, we still do not know why it happens. We cannot predict it, we cannot prevent it and we do not understand it.
I first came to this issue through a family in my constituency. At one of my surgeries, I met a grandmother whose 13-month-old grandson had died suddenly. The family asked me to share their story in the hope that no other family would have to go through what they have gone through. I pay tribute to the grandmother and her daughter for that courage. At their request, I will not use their names today.
It was an ordinary morning like any other day. Mum put her toddler down for his nap. He was well, and there were no signs of illness—no warning—but he never woke up. That is the reality of SUDC: there is no build-up or explanation, just a moment that changes everything. The impact on that family has been devastating. Alongside the shock and grief came something else: the cruelty of not knowing why. That uncertainty compounded their trauma, and the emotional toll became so overwhelming that it caused severe mental health challenges.
It is a pleasure to serve under your chairship, Sir John. I thank the hon. Member for Rossendale and Darwen (Andy MacNae) for securing this very important debate.
First, I would like to recognise the work done by organisations such as SUDC UK that have campaigned on this issue to raise awareness of a very tragic problem. Their work is even more admirable given that so many of the people involved have themselves been affected by SUDC. The loss of a child is one of the worst things that can happen to a parent, but to lose a child and never know why they passed away must be agonising.
Sadly, SUDC is an issue that hits many families across the UK—around 40 children are lost to it every year. At the start of this year, I met two constituents whose son passed away from sudden unexpected death in childhood in 2024. I was struck by their bravery to share their story with me in the face of such tragedy. Hearing about the pain of losing their child and not knowing why, I was struck again by their strength and determination that something needed to be done. In my meeting with them, it was made clear that a serious lack of research and awareness around SUDC has left parents without support or answers.
The parents are calling for research to focus: on detailed post-mortem studies; assessing hidden biological vulnerabilities by focusing on genomic sequencing and family history; neurology and sleep-related mechanisms; and environmental and situational factors. Sadly, most active research appears to be taking place in the US, with very little happening here in the UK. I call on the Government to remove barriers to global research talent coming to the UK, and commit to a decade-long programme of public investment in research and development.
Shockingly, SUDC UK found that just half of the families affected by SUDC were assigned a bereavement key worker. Many parents had distressing experiences when dealing with authorities who offered little support. To increase support for families, Liberal Democrats are calling for the funding for bereavement support payments to be doubled, reversing cuts by the previous Government.

That fear leads families to delay trying for another child, even though a new life could be a source of hope and healing amid loss. It is completely rational for a parent to fear, if one of their seemingly healthy children has died without explanation, that their other seemingly healthy children could also be at risk. That is why genomic and cardiac screening is so important: it not only informs research but protects surviving siblings. For some families, genetic analysis has revealed risks requiring vital preventive treatment, yet those crucial tests are currently available only after the post-mortem process concludes, which brings me to the next point.
Paediatric pathology is in crisis, as summarised in a recent report by the Royal College of Pathologists. Families experiencing SUDC routinely wait nine to 12 months, or sometimes longer, for a post-mortem conclusion. During that time, they live in fear—fear for their surviving children, fear of future pregnancies, fear of the unknown. Their grief is suspended and their lives are on hold. Only after that traumatic wait can they finally access genomic testing or cardiac screening to safeguard their children.
After speaking with Brian and with Nikki, I would like to outline the typical timeline for a family affected by SUDC. Your child is fine. Then they die, leaving you traumatised and in shock. The child is taken away from you, and you have no control over what is happening. The ensuing process is statutory, but the response is based on evidence from infant death and so is suboptimal. After scary interactions with the police and in deep shock, you return home to deafening silence or to the child’s siblings, to whom you must tell the very worst news. Then you wait. You do not wait one week or two. You do not wait a month or even six. You most likely wait nine to 12 months. If the pathology is complex, you wait even longer. Throughout the whole wait, you are scared for your other children and scared to get pregnant again. You put your life and your grief on hold. Only then, often about a year later, do you receive the post-mortem report. You have been desperately waiting for this moment, but now it is here it brings back all the trauma of losing your child, and only now are you eligible to see whether anything hereditary is putting other family members at risk.
This is inhumane. When we lost our daughter, we had the answers right away, yet the trauma is still with us. I cannot fathom what it would be like to sit in deafening silence for months, and the long-term damage that that could do. This must change. A national plan should establish faster pathways for cases in which timely information directly affects vulnerable bereaved families and child safety.
I went to see them just this last weekend to catch up with them and check in, and I reiterated to them that I will continue, as their Member of Parliament, to do all I can to raise this issue on their behalf. I was glad to see that they are working united as a family to keep this issue going. Over the last three years, they have worked together to raise over £220,000 in total for local good causes.
Sudden unexplained death in childhood is the fourth leading category of death in children aged one to four in England and Wales. Approximately 40 children are affected by SUDC in the UK each year: one to two seemingly healthy children pass away every fortnight, often going to sleep and never waking up again. As seen in cases such as Jack’s, SUDC does not just affect young children under one year old; more one to nine-year-olds die of sudden unexplained death than as a result of road traffic accidents, drowning or fires.
Published epidemiology data suggests a common profile for children affected by SUDC. Most commonly, they are one to two years old and male. Most worryingly, they die unwitnessed and alone as they sleep. The children’s development is often normal, and their vaccinations are normally up to date.
The death of a child is always a tragedy. Sudden unexplained death in childhood is one of the most under-recognised medical tragedies, and simply not enough support is provided for many of the affected families. Cheryl and Darren received a year of support from the NHS following Jack’s death. They have both sought counselling, and the trauma still lives with them today.
I commend the work done by charities such as SUDC UK and Martin House children’s hospice in providing support for those impacted by sudden unexplained death in childhood. However, we cannot just rely on the good work of charities and volunteers. Despite their efforts, the delays in small charity-funded research into preventing these deaths remains completely unacceptable. One hundred and twenty seemingly healthy children have died without explanation since the last SUDC debate three years ago, which I took part in.
Although we are a long way from prevention, it is vital to develop a well-defined and co-ordinated national plan to gain better insight into the causes of SUDC and to raise awareness. There have been 13,000 publications on SIDS—unexplained deaths under 12 months—versus 100 publications on SUDC. There needs to be a co-ordinated and planned movement because, as I am sure the Minister is aware, a small amount of research will not move the dial. There also needs to be better and longer-term support, available free of charge, for families such as Cheryl, Darren and Louis, to help them to come to terms with the deep sense of loss, anguish and grief that comes with the death of a child.
At the very point the family needed care, clarity and compassion, the system repeatedly let them down. They endured 13 months of pain awaiting a post-mortem. They received phone calls from medical professionals without warning, the day after their child died. Professionals used insensitive language, causing further harm. They were given inconsistent and incorrect information. At one stage, they were told the post-mortem had been completed while the child was still in the hospital’s care.
This is not just about delay; it is about dignity. Sadly, that family’s experience is far from unique. Families across the country report similar patterns: long periods of silence followed by a sudden, distressing and poorly timed communication. They find themselves chasing answers when they should be supported, and in some cases having to explain SUDC to professionals. At a time of profound trauma, families are left to carry the burden alone. As is so often the case, those with less financial resources face even greater barriers, whether in accessing counselling, navigating systems or challenging poor care.
Traumatic grief demands trauma-informed care, but too often it is missing. Organisations such as SUDC UK are stepping in to support families, raise awareness and push for answers, but the reality is that they are doing so in the absence of a clear, co-ordinated national approach. That gap should concern us all.
At its heart, this points to a wider issue. SUDC remains one of the most unrecognised medical tragedies we face. Awareness is low, research is limited, and without understanding there can be no prevention. We cannot accept that. Families deserve answers, consistency and to be treated with care at every step. That means a system that is joined up, where knowledge is shared, professionals are trained and support is not dependent on postcode or circumstance.
It also means addressing the workforce challenges we face. There is a severe shortage of paediatric pathologists in this country, and in some regions there are none at all. That is a key reason why families are waiting for months, and sometimes more than a year, for answers. After hearing about my constituent’s experience, I met with the Royal College of Pathologists, and I continue to support its work on recruitment, training and retention.
The truth is that families should not face further trauma because the system does not have the capacity to respond, so I ask the Minister to take four steps: to develop a national plan for SUDC, formulated by Ministers working with officials and scientific experts, as a matter of urgency; to commit to regular reporting at a minimum of every two years, so that we can track progress and hold ourselves accountable; to ensure that clear, accessible information for families is available through the NHS website and other portals, including the NHS knowledge and library hub for professionals; and to move quickly on implementing the recommendations of the paediatric and perinatal pathology workforce report, so that we can achieve quicker post-mortem times and safeguard genetic information and other data to support further research.
This is about every family, in Warrington South and across the country, who are living with unimaginable loss and deserve better from the system around them. We cannot change what has happened to them, but we can change what happens next. On behalf of my constituents, and on behalf of every family who has endured the unimaginable agony of losing a child suddenly and without explanation, I urge the Minister to act now.
I would like to end by again thanking my constituents for giving me their time to share their story with me and highlighting the clear need for urgent change.
