Tan, it sounds very similar to how Ash was at the time.
From our experience it was more of a comfort thing than a hunger thing.
Ash was on one solids meal at the time but even when she was taking more she was still waking the same just cause it became habit.
We started slowly cutting out one feed at a time. Its actually only been the last month or so that she's actually started sleeping thru!
Good luck with it all.
