How to use this chart

Find your baby's current age in the left column. The 'per feeding' range is a typical amount for a healthy baby that age. Multiply by the number of feeds per day to get the daily total — or use the calculator on the home page to get a personalised estimate in seconds.

Weight-based amounts

Once you know your baby's weight, a more accurate method is to give 150–180 mL per kg of body weight per day (or ~2.5 fl oz per lb per day in imperial units). The calculator uses this method automatically when you enter a weight.

Daily maximum

Healthy babies rarely need more than 960 mL (32 fl oz) per day. If your baby seems to need more than this, speak with your pediatrician — it may be a sign they're ready for solid foods.
