Speak to your doctor about any suspected allergic reaction your baby has to a new food. If the reaction is mild, the doctor will probably instruct you to wait 1 week, then try the food again. If the reaction recurs, your baby probably can't tolerate that food. There are some foods that are generally withheld until later. For example, pediatricians usually recommend holding off on egg whites, cow's milk, citrus fruits and juices, and honey until after a baby's first birthday.
Citrus is highly acidic and can cause painful diaper rashes for a baby.
Honey may contain certain spores that, while harmless to adults, can cause botulism in babies. Never give your baby honey. With the hectic pace of modern family life, most parents opt for commercially prepared baby foods at first. They come in small, convenient containers, and manufacturers must meet strict safety and nutrition guidelines. Protect your baby and the rest of your family from foodborne illness by following the rules for food safety.
