My 16 week old was a terrible sleeper to begin with, then became pretty good- going to sleep at 7pm, waking once for a feed and then up for the day around 6/630.
Now her wake up time is creeping forward every day. She goes to sleep around 7pm, wakes around midnight for a feed and then at 5am on the dot is awake for the day. If I feed her and keep it as a night feed she still won't go back to sleep.
She has a 90 minute morning nap and a two hour lunchtime nap and about a 20/30 minute afternoon nap.
How can I get her to start sleeping in a bit later?
