Create new guidance for schools as well as parents on screen time for children

The government have provided new guidance with evidence to back the reduction of screen time for children aged 2-5 to 1 hour per day for parents. However, it has not considered the time spent on screens during the school day which can often exceed 1 hour. Educational or not it’s still screen time. The Government has said that evidence backs the guidance that children shouldn't use screens for more than 1 hour so why is this only for parents to follow and not schools. There should be transparency from schools to parents about screen time at school and guidance for them to follow as well.
