Hi I'm a mummy of a 6 month old. He's always a bad sleeper since birth. I'm stressing ova whether to do sleep training with him. I can't do 'drowsy but awake' he won't play ball with that. Is it necessary to sleep train? Naps are half hour 4 times a day which he seems happy with. Please any advice wud be grateful. My head is about to explode and need to stop worrying. X
