its difficult at this age to know what to do about sleeplesness and getting out of bed though i dont think it helps him having the playstation/ computer in his room, is there anyway you could put these in a different room to where he sleeps? is he tired enough to sleep? how about putting his bedtime an hour later? bedtime routine a small snack such as a piece of toast/ a bowl of cereal , bath and a story, he's still young enough to enjoy the cuddles and closeness from mum. instead of star chart which may seem a bit babyish to him how about 50p a night if he stays quietly in bed each night, if theres some toy or game he really wants this could be a real incentive to save up for it. hope some of these suggestions help, dont forget lots of encouragement and attention during the day and let him know how much you love him, good luck
