How many ounces does a 2 month old usually drink (breastfed) in a typical feeding?

I can't answer that because there is no "typical" amount for babies, especially newborns. Mine would drain both of my breasts if she was really hungry, or hardly nothing at all if she wasn't. It depends on the baby, their size/weight, and what's normal for them.

Mine could drink 2 - 4 ounces every 2 - 4 hours. The only way that I verified this was pumping into a bottle and then feeding her to see how much was being consumed. The success to breast feeding and maintaining milk production is to let your baby nurse every 2 - 4 hours and drinking lots of water. Pumping more than nursing can reduce your milk production.

I think about 2-4 ounces roughly every 3 hours. One way to establish how much your baby drinks is to contact the lactation consultant at your nearby hospital. Our nearby hospital offers a breastfeeding class weekly. You can stop in, weigh your baby, feed your baby, and then re-weigh your baby. This process allows you to see how much your baby is eating in one sitting. It helped put my mind at easy.

THE BREASTFEEDING ANSWER BOOK says 2-2.5 ounces per pound of body weight per 24hours. This is for the healthy, well-gaining baby. An additional 1-2 ounces per pound may be needed for slow gaining babies.

My sister had about 3 ounces as a baby. It increases as the age of the infant also increases. 2-4 ounces should be it.
