Have just moved my 2 yr 7 m DS from a cot into his big bed. First few days went fine and he settles to sleep quite well (albeit with a low light on which he never used to have in a cot..) - but then when he stirs during the night he comes fully awake, puts all the lights on and starts playing, chatting, singing - I wouldn't mind if this was half an hour and then he dropped off again, but oh no, this can be for hours and hours - woke up last night at 3 and that was it for the rest of the night! Plus other random behaviour - screaming if it's dark and he wakes up and so on. Any ideas or do we just have to stick with it and deal with sleep deprivation - will it get better?!?!?
