I am 8 days PP and barely producing 0.25 oz of milk when pumping (both breasts combined). I see all these other posts of people getting 3oz+ each time they pump and they are worried about it. I can't even get 1oz. What could I possibly be doing wrong? As of today I'm starting to pump every 2 hours instead of just after everytime she eats to see if that helps. We go to the pediatrician on Thursday to see if our little one is gaining weight or not. She currently eats anywhere from every 45 mins to every 3 hours (it's exhausting). How do I know she is getting what she needs?

Did anyone else struggle like this? I'm not opposed to starting formula as I believe fed is best but my husband really wants me to stick it out.
