5.5 month old early morning wakings and lie ins

[Madallie]

Just wondered if anyone had any advice. Dd is 5.5 months old and has been sleeping really well, going from about 7pm to 5/5.30am then a feed then back down Til about 8/9am. This is so different to dd1 and I know how lucky we have been. I have just noticed however that she has started to wake for an hour or more in the early hours leading up to her early feed. She's not looking for food or crying and seems quite content. She then has her feed and then as I say goes back to sleep until around 8/9am. Yesterday it was almost 10 am. I just wondered whether anyone thnks it could be that fact that I let her sleep in so late in the mornings that is causing or maintaining these night/early morning wakings?

Should I be getting her up at a set time each morning, say 7/7.30 to try and encourage her to sleep through and not be able to catch up via these ling lie ins? I would rather her just sleep soundly through the night than sleep in late in the mornings.

Any experience or advise?
