Hi! So my 9 month old baby has been geberally sleeping through the night since 7 months. Usually 6/7pm to 6 or 6.30 am. Which is great and seemed fine to us. Now she has been waking up at 5 or 5.30 for the past 10 days . This happens regardless of her bedtime . So anything between 6 and 7pm. Impossible to get her back to sleep. It's like a new wake up time. We tried feeding/leaving her (She normally self soothes if she wants to sleep). She has started having a 40 minute nap instead at 8 am. How can we get her to sleep an hour longer at 5 am rather than nap later or is this just too much to ask ? I was wondering if this was a little regression. Any tips ? Thanks!
