My DD is 13 months and a great sleeper in terms of sttn from 630am and is easy to put down awake for naps and bed. The problem is that she sometimes wakes anywhere between 5 and 6 and she litterally screams the house down. Why is this? I thought she was getting fed up of sleeping bag so used a duvet last night which seemed worse this morning. I always remember by DS waking a cooing in his cot for a bit. I know all babes and toddlers are different I just don't know why she screams so much in the morning. She has a very strong character so maybe it's just her. Does anyone else have experience of this and does this change?
