Thanks so much everyone.

You wouldn't beleive it ...

Lily has slept through (10-11hrs) for the last 3 nights

Let's hope she keeps it up.

And, no, I didn't change anything. Oh, I was waking her up at 8.30pm for a top up feed, but I cut that out, and she slept through about 2-3 days after I stopped that.

I feed her every 3-3.5 hours a day, depending on her sleeps. I always feed her before I put her down for a nap (whether she needs it or not) and she has increased her day sleeps up to 4-5 hours in the day now too.
