In the final of the big questions for this series, Jo’s focus is on a serious but hidden threat to the health of the UK’s children – not getting enough sleep. Life is becoming busier and bedtimes are getting later – but what effect is a few hours less sleep really having on our children’s abilities, at school and at home. Working with the UK’s leading expert in child sleep issues, Dr. Cathy Hill, Jo is going to take over the sleep habits of a group of ten year olds to find out exactly what is the impact of insufficient sleep. Jo also meets four year old Michael who rules the family roost. He has learnt to play his parents against each other and scream until he gets whatever he wants – but as he prepares to start school is it too late to instill discipline? Jo doesn’t think so.
