how much milk does a baby need in a day

Wondering how much milk your baby needs a day? This handy chart will tell you exactly how much breast milk or formula your baby needs to drink in a 24-hour period.

When a baby is born their tummy is around the size of a shooter marble and can only hold 5-7mls of milk. By day 2 it can hold 25-27mls and by day 10 their tummy is the size of a chicken egg and can accommodate 60-80mls.

After the first week, a newborn needs approximately 150mls per kg of their body weight per day. This is then divided by about 8 feeds per day (every 3 hours). The chart below will help you determine your baby’s milk needs and requirements according to their weight.
