Soy formula is likely safe for most healthy babies. It's just as nutritious as other types of formula and likely the most beneficial choice for vegan families and babies with galactosemia or hereditary lactase deficiency.

2. Why would a baby need soy formula?

According to AAP, the only real indications for soy formula use are for infants with congenital galactosemia, for use by families who are strict vegans, or infants who are truly lactose intolerant. For more information, read AAP's May 2008 statement Use of Soy Protein-Based Formulas in Infant Feeding.
