How much milk do I pump?

isabella

So I have a 5 week old and I breastfeed her. I am pumping because my milk supply is low so I’m trying to make more. I’m not sure how many ounces my baby even drinks at 5 weeks🤷🏻‍♀️ and I want to put the amount that she eats in the milk storage bags. Seems like now she’s not satisfied with 2oz.
