How much is she eating? Help!

Katie

Hi mommy’s!

I am 3.5 pp and FTM here! I feel like I should have this figured out by now... We are EBF but I’m curious how do I know how much she is eating per feed? She eats roughly ever 2 hours. I have a stash starting to build up and would like my husband to be able to bottle feed her but I don’t have any idea of how many ouches she would need. Is there any general amount a 8.5lb baby eats per feed?

TIA!
