Primary school head forced to warn against gaming and late night TV Mrs Morgan also addresses the issue of children having televisions in their rooms: "As more children have televisions in their rooms, we are finding that some are also watching TV until late.'" She also writes to parents directly: "Obviously, we can only talk to children about good habits and about the need for a definitive amount of sleep at their age. We need cooperation of parents and carers to ensure that all our children arrive at school in the best possible frame of mind for learning. The late night gaming, which included playing "live" versions online, was also having an impact on punctuality at the school as some were too tired to get up in the morning. Mrs Morgan, who said that it was particularly important for year six pupils, added: "I empathise with parents and carers, having gone through many battles of wills with my own children - they won't thank you for it at the time, but they will later." Georgie Kennedy from Brighton and Hove Parents' Forum agreed that parents needed to take action. She said: 'There is a huge danger with online games. There are all sorts of things online especially if these children are accessing it in their bedrooms. And in the virtual reality world they lose out on interacting with others. If there is no discipline in the home how will they get on in later life? Everyone needs to hear 'no' at some point. The news comes after another primary school in Sussex issues a warning to parents about children playing in violent video games. Meeching Valley Primary School in Newhaven said last month that kids as young as seven or eight were acting out on-screen violence in the playground. Primary school children range from age 4 to 11.
