Babies will regulate how much they eat according to their needs, so this is just a guide. On average, your baby should take in about 2½ ounces of formula a day for every pound of body weight. When caring for your twins, start by choosing double the usual monthly supply. As you evaluate how each baby feeds, you can change the amount of infant formula you order based on their needs. Always talk to your pediatrician if you have questions about your baby’s specific needs.
