Question: how much does a 4 month old baby drink?
Answer: At 4 months, your baby may be taking 4-6 ounces (120-180 milliliters) at each feeding, depending on the frequency of feedings and his or her size. By 6 months, your baby may be taking 6-8 ounces (180-230 milliliters) every 4 to 5 hours. This also depends on whether you've introduced any baby food.
