A: It's possible your daughter has decided she doesn’t like her current formula. If that’s the case, she might prefer another type. If she’s currently drinking a formula made from cow’s milk, she might have developed an intolerance to the proteins in this type of milk. It could be giving her an upset stomach, even if she doesn’t vomit or develop diarrhea after drinking it. If she’s drinking a soy-based formula, she could have developed an intolerance or allergy to soy protein. Some babies who don’t tolerate formula made with cow’s milk also have trouble tolerating soy-based formula. Babies who can’t drink either of these formulas are often switched to protein hydrosylate formulas, often called hypoallergenic formulas, which are easier to digest and less likely to cause allergic reactions.
Babies need to drink breast milk or infant formula for the first 12 months of life to ensure they’re getting the right nutrients to support proper growth and development, so it’s still too early to give up on formula. At this point, it’s probably wise to make an appointment with the pediatrician to discuss your baby's refusal to drink formula. Working together, you and your pediatrician will undoubtedly find a solution—and a formula—that is just right for your daughter.
