It's been around for 40 years, but soy formula has suddenly come under fire: why: It's being blamed for early puberty, thyroid disorders, ADD, and more.
What we know: Studies remain inconclusive. For now, the AAP considers soy safe for full-term infants.
Who should drink it: Few babies need to. There's a lactose-free cow's milk formula for infants with lactose intolerance, and hydrolyzed or amino acid-based kinds for allergic kids. That makes soy necessary only if you don't want your child to have animal protein for religious or ethical reasons, or if your baby has galactosemia, a rare hereditary condition.
