Nighttime waking

My LO is just over 7 weeks now and will sleep a long stretch at the beginning of the night, typically 9pm-1/2am ish when she wakes up for a 4-5oz bottle, but after that she doesn’t settle very well again.

I manage to get her to sleep after being awake for around an hour, then after that she wakes every 45-60 minutes but doesn’t even want milk.

Any suggestions on how I can help her through this stage so she can get more sleep at night, or is it something I’m just going to have to wait out?!
