Hi, I am new to mumsnet and haven't posted before! I have a 4 and a half month old DD who has slept through the night in her cot from 11 weeks - we have been lucky so far! In the last week or so she has started waking an hour or so earlier than usual, at 6-6.30am - not sure why. The last 2 nights she has also woken in the night. She doesn't cry though, just chats in her cot! If I leave her to it she goes quiet after about 10-15mins, when I go in to check she is asleep again! Has anyone else had this with their babies? I wouldn't leave her if she sounded distressed but she doesn't, and she seems fine when I go to get her up in the morning. She is quite vocal in the day, chats and squeals a lot - attracts a lot of attention in the supermarket!!
