Baby that young should be fed every 2-3 hourly. Even when the baby is asleep at night. It is important for the baby to receive the nutrient. They should be drinking at least about 50ml each time.

A baby infant feeds can be variable. I would usually use this general formula to calculate the feeds. Multiply current weight by 150ml to obtain the total feed volume per day. Divide this amount by the number of feeds to obtain the feed volume. Eg. 4 kg child would require 4x150ml= 600ml/day. If given 8 feeds per day, each feed would be 600ml/8 = 75ml. The advice is kept general and not a substitute for a consultation. Kindly consult your doctor or pediatrician as a detailed history and examination is important to come to a diagnosis and treatment plan.

Mine drank every 2-3hrs. I only wake her to feed in day. And let her self wake during night. Drank about 60ml for mine.
