The most important step toward helping your child is to remove all cow’s milk products from their diet. If you’re breastfeeding your baby, you’ll need to stop eating dairy products, too.
For formula fed baby, cow’s milk can be replaced with a special formula such as hypoallergenic formulas (extensively hydrolyzed formulas or amino acid-based formulas)— your doctor will recommend the type that is best for your child. Using goat's milk as a treatment for cow milk protein intolerance (CMPI) is generally not recommended. Goat's milk contains proteins that are structurally similar to those in cow's milk. Many children who are allergic to cow’s milk proteins will also react to goat’s milk.
You’ll need to read food labels closely to make sure the foods don’t contain cow’s milk. Between 6 months and one year, your doctor may recommend that you start slowly reintroducing cow’s milk products to your child’s diet. Be sure to watch closely for CMPI symptoms and stop feeding milk products if they appear.
