Hi mama! At 11 weeks, most babies drink around 4-6 oz per feeding, but honestly it really depends on your baby, some of my mum friends' babies were content with 4 oz while others needed closer to 6 or even 7 oz, so you'll know best by watching kung gaano siya satisfied after feeding. The easiest way is to follow your baby's hunger cues lang, if they're still rooting or fussy after, they might need a bit more, pero if they're content and sleeping well, you're doing great! Every baby is different, so don't stress too much about hitting an exact number.
