When you begin introducing solid foods to a baby, do so slowly and one at a time. That way, it is easier to identify potential food allergies.
The American Academy of Pediatrics recommends that you start trying solid foods when your baby is between 4 and 6 months old. Many parents start with rice cereal, then gradually move to fruits and vegetables.
If you start three different new foods on the same day and your child develops a reaction, it can be difficult to tell which food was the culprit. Instead, wait three to five days after introducing one new food before trying another.
If your child develops hives; a rash; has trouble breathing; vomiting or swelling in the tongue, lips or face, seek medical treatment right away. Your child may be suffering an allergic reaction.
