Seriously, it is as if a switch was turned on at the weekend when it was his birthday and now he will not stay in bed
It now seems to have gone quiet upstairs but it is 2 hours after his normal bedtime.
It is one excuse after another and he is in and out of his bedroom - need a drink, need a wee, can't sleep, there is a funny noise...this happens when he goes to bed and then is repeated at some ridiculous time in the early hours of the morning 
What do I do? I have warned him that if he comes out of his bedroom (unless it is actually an emergency) again tonight, his DS will be put away tomorrow and I will repeat this every night. Anything else we can do??
