With DD1, I started at 8 weeks with the dream feed, it took 3-4 weeks to get her to take a full feed, every DF. I had loads of problems with loud neighbors at the time but once we moved, on good nights she would be in bed at 8pm/ DF-10:30pm/ NF- 4:30-5am/ WU-7:30-8am.
With DD2 (5weeks) we started DF @ 10:45pm last week (or the week before,can't remember) and some nights she takes 3oz some 2oz. She still gets up between 2-3am for another bottle.
It just takes time, just think your laying the stones for STTN within a few short weeks
