Most pediatricians advise parents to wait until baby is about six months old before trying baby foods to supplement formula. But is six months a hard and fast rule that all parents and babies should adhere to. Each baby develops at a different rate, which is why the handouts from the pediatrician’s office have age ranges for developmental skills. Your baby will begin to show you when he is ready to start on foods. Remember though, to stick to one food for about a week when introducing new foods. For example, if you decide to start with peas, then feed your baby just peas for the first week. This will help you to pin down allergies early. Most experts also agree that parents should stick with the same category of food when introducing new foods. So if you start with peas, your next choice would be another vegetable, such as green beans. Once you have finished all of the vegetables you want to introduce to baby, you switch to fruits. Meats and desserts are always last on the list. Meats are more difficult to digest and desserts may contain sugars that baby does not need.
