Question: how many ounces of breastmilk does a 3 week old drink?
Answer: Between the second and sixth day, your milk production will increase. Your newborn will probably take about 2 to 3 ounces every 3 hours (14 to 28 ounces per day). From 1 month to 6 months of age, your baby will take an average of 3 to 3 1/2 ounces every three hours (25 oz to 26 oz of breast milk each day).
