hi doctor, I thought start to using breast pump to express milk. can you pls clarify how much of milk needed for 1 month 10 days old baby boy per feed.

A. On average, a newborn drinks about 1.5–3 ounces (45–90 milliliters) every 2–3 hours. This amount increases as your baby grows and can take more at each feeding. At about 2 months, your baby may drink about 4–5 ounces (120–150 milliliters) every 3–4 hours.
