## How much does infant formula cost?

We estimate that a baby needs about 300 litres (80 U.S. liquid gallons) of infant formula in the first year of life. This number can be used to calculate the local cost of infant formula. Families will have other associated costs, including the cost of bottles, thermometers, equipment washing, and sterilizing. The cost of infant formula leads some families to over-dilute infant formula, a dangerous practice that can lead to underfed babies and low levels of salt (sodium) in the baby’s blood. Store-brand infant formula is cheaper than name-brand formula and the ingredients are very similar. Powdered infant formula is cheaper than ready-to-use. Breastfeeding families must pay for the additional food needed to make milk (about 600 calories each day) and any breastfeeding equipment they choose to buy.
