Just curious, how much does everyone’s baby weigh and how much milk do they drink a day? I’m always worried my little guy doesn’t drink enough. He’s about 12 lbs and he drinks 20-25 oz a day usually. I exclusively pump, so not sure if it matters on the amount of breast milk vs. formula. He’ll be 4 months in a few days.
