Often genetically inherited, food allergies can be serious business. Babies have delicate immune systems that aren't yet equipped to handle potential allergens. As a preventative measure, pediatricians advise against exposing babies to certain foods before the age of two or three.

It's impossible to predict what a baby will be allergic to so when introducing a new food, be on the look out for these symptoms:

• Hives
• Watery eyes, runny nose
• Dry patches of skin on the face, kneecaps, and elbows
• Swelling of the face, mouth, and lips
• Vomiting
• Diarrhea

Call 911 immediately if after eating, your baby:

• Has a hard time breathing
• Loses consciousness

These symptoms could indicate a severe allergic reaction and require immediate emergency treatment.

If you suspect that your baby has a food allergy, visit a pediatric allergist and have your child tested. The allergist will administer a test to help pinpoint which food causes the reaction and determine if the symptoms are indeed an allergy or if it's a digestive issue, which would require a visit to the gastroenterologist.

If your child is indeed allergic to a certain food, avoiding the food is of the utmost importance. This can be tricky because a lot of food ingredients are hidden. Be extra careful and exercise vigilance in reading all food labels and ask about ingredients in restaurants. If you are still nursing, you'll have to give up the food as well, since allergens can be passed through breast milk.

To prevent a possible allergic reaction, be sure to avoid feeding your child these ingredients before the age of two:

• Citrus
• Egg whites
• Honey
• Peanut butter
• Wheat or wheat products
• Shellfish
• Nuts

And if food allergies run in your family, it might be worth having your child tested...just in case.
