Question: how many ounces of milk should a five month old baby drink?
Answer: Typically, a baby needs about 25 ounces of breast milk per day. So you'll need to divide that by how many feedings your baby typically has. So if you feed baby about eight times per day, he should get about 3.1 ounces of breast milk at each feeding. That's how much milk a 5-month-old should drink.
