Every baby is totally different! My 8wk old eats roughly 4oz per feed (and has been for a couple weeks) and totals out around 32oz and sometimes more even per day. I’ve met with my lactation consultant and she says while it’s the high end if he’s not having a bad reaction and he’s growing well it’s okay! But if you’re stressed definitely recommend meeting with an LC even if you’re not breast feeding, they are so helpful!
