Cow's Milk-Based Formula
Most infants should be able to tolerate a standard cow’s milk formula such as Enfamil® Premium, Similac® Advance, or Good Start®. These formulas use cow's milk as a base, but have been modeled after breast milk. They are available in ready-to-feed cans, liquid concentrate, and powder. These formulas have lactose as the carbohydrate (sugar) source. However, each brand has a low-lactose or lactose-free version that is available.
Soy-based infant formulas can provide adequate nutrition for your infant. ProSobee®, Isomil®, and Good Start Soy® are soy formulas. Soy-based infant formulas can be used if an infant is not tolerating the sugar (lactose) found in cow's milk-based formulas. Soy formulas do not contain lactose as the sugar source. Sometimes, soy formulas are used if your infant is not tolerating cow's milk protein. However, infants who are allergic to cow's milk formula can also be allergic to soy-based formulas. Consult your baby's physician before changing his or her formula.
These are special formulas usually used if your baby is unable to tolerate standard infant formula. Alimentum®, Nutramigen® and Pregestimil® are examples of protein hydrolysate formulas. These formulas are more expensive than standard formulas. Often these formulas are used if your baby has a cow's milk protein allergy or if he or she is unable to digest a standard infant formula. Consult your physician before using these formulas.
