Question: can only pump 1 oz milk?
Answer: It is typical for a mother who is breastfeeding full-time to be able to pump around 1/2 to 2 ounces total (for both breasts) per pumping session. ... It is not unusual to need to pump 2-3 times to get enough milk for one feeding for baby (remember that the pump cannot get as much milk as a baby who nurses effectively).
