Next: Make Your Child Food Smart

Not only do you need to be careful about keeping problem foods out of your house, you also need to teach your child to steer clear of them in other settings. "You don't want to scare him," Dr. Sicherer cautions. Just calmly explain, "Mommy and Daddy don't want you to feel sick, so it's important that you take food only from us and Grandma."

Dr. Sicherer even suggests role-playing together  -- for instance, by pretending to be a visitor offering him a cookie. If he starts to accept it, say something like "Uh-oh. Remember what we talked about  -- visitor doesn't know about your allergies."

You'll also need to get used to explaining your child's dietary restrictions when you eat out. A recent survey found that restaurant workers generally don't realize that something as small as a cross-contaminated serving spoon or frying pan could trigger a severe reaction.

"I Want What They're Having!"

For young children, not being allowed to eat what other kids do can be upsetting. When Sabrina Sciarrotta was 18 months, "she was so eager to have everything her big sister, Julia, had," recalls her mom, Monica, of Brea, California. "But while Julia was fine with dairy, Sabrina got headaches and broke out in rashes." To avoid a conflict, Sciarrotta now doles out Julia's yogurt and milk only when Sabrina is napping.

There will inevitably be times, though  -- at birthday parties, for instance  -- when your child can't ignore her limitations. Get in the habit of sending your child to such events with "safe" food alternatives. At school, be sure to explain her food allergy to her teachers and the nurse. If your child has a severe allergy, see if her school will even send notes home to her classmates' parents, explaining that certain foods shouldn't be sent in for sharing.

Outgrowing Food Allergies

The good news is that many children's food allergies go away by age 5. In fact, milk, egg, wheat, and soy allergies disappear nearly 85 percent of the time. So if your child has sworn off, say, soy for several years, ask the doctor if it's a good idea to reintroduce it to him again. She may suggest repeat allergy tests under medical supervision.

While you're still dealing with food allergies, however, remember that "life should not be viewed as a mine field," says Dr. Sicherer. Wood agrees: "We try to protect Daniel while letting him live a normal life."
