I believe 2-8 weeks it’s between 450ml-735ml between 6 or more feeds but like Chloe said every baby is different if they want more they will give cues if they want less they won’t finish the bottle! As long as they are putting on weight my midwife said around 20g a day is a good amount! X

Every baby is different, my baby is 2 weeks and I'm exclusively pumping he takes 120mls between every 2 and 4 hours .x
