Is it normal?

Jennifer❄ • My husband and I have a beautiful daughter who was born in 2016. Now we are wanting to expand our family.
Is it normal for a 1 month old to eat 7-9oz before bed but eat about 5-6oz every other time. I mostly breastfeed but I supplement 1-2 formula bottles because she had a bad case of jaundice. I also pump a battle at bed time so I can make sure she is getting enough.
