3 days old- diaper count and feeding amount

Emilee

My baby is 3 days old. Yesterday, she had two poop diapers and only one wet diaper. I was so concerned that I started pumping my colostrum/transition milk during the night feedings so that I could see how much she is eating. She keeps falling asleep while feeding from the breast and I was afraid she wasn’t getting enough.

I am getting about 15 ml from pumping both sides for 20 minutes. Should I supplement with formula? Is it possible that she peed in her diaper yesterday at some point and I didn’t see it?

First time mom here and very anxious about giving her everything she needs. (It also doesn’t help that people around me keep googling things and telling them to me.) I feel like such a bad mom for not being able to give her more. Please be kind with comments.
