Need help!!

Two things ladies !

1st my baby’s eating schedule is all out of wack. I was told I’m over feeding her but I don’t think I am because she’s moving as if she’s hungry (sucking hands,balled up fist and turning head towards breast when I’m holding her). I pump and breast feed but it just seems as if it’s never enough. This morning I breastfed her for 20 minutes and about 1.5 hours later she had a 4.25 oz bottle. She fell asleep for about another 1.5 hours and woke up very hungry acting. I don’t know what to do at this point. Is she hungry or is something else going on?

2nd I would love tips on upping my milk supply as well. It’s beginning to fluctuate day to day now and I want it a bit more consistent.
