He was so good before, he would go in his cot and chat to his toys and drift off to sleep on his own with his lullaby music, no problems! Then in the past week he has started WAILING when I put him in his cot for bed. He still enjoys the routine before bed and tonight when I asked him if he wanted to go to bed he took himself up to his room and pulled his grobag out etc. But he has now been wailing for almost an hour! I've gone up intermittently to reassure him but it seems to make him worse.
We have brought him back downstairs for a bit the past few nights to calm him down and he then goes to sleep no probs but I don't want him to associate wailing with getting his own way and coming back down to watch a bit of TV with mummy and daddy either. Help?!
