Allergies to Food

Your child is more likely to have a food allergy if a parent, brother or sister has an allergy.

Food allergies are most common in infants and preschoolers. Many children will outgrow a food allergy, but some will have an allergy for life.

Offer new foods to your child one at a time and wait a few days before offering another new one. Watch for allergic reactions when you offer new foods. Some signs of food allergy include rash, vomiting, diarrhea, itchy or watery eyes, swelling of the mouth or face, or breathing problems.

If your child has a bad reaction to eating a food, or if you think your child may have a food allergy, stop offering that food and contact your family doctor. Your doctor may want to refer your child to an allergist for testing.

It is important to get a proper diagnosis of a food allergy before eliminating a food from your child's diet. If your child must avoid a food, you may want to talk to a registered dietitian. A dietitian can help you find foods that will replace the nutrients in the foods your child is not eating.

Babies

Exclusive breastfeeding for the first six months decreases the risk of food allergies. A baby is less likely to have a food allergy if foods are introduced after six months of age.

Preschool & School-Age Children

Schools in Ontario are required by law to have a policy and procedures for handling children's allergies. If your child has a food allergy, contact the school and talk to a teacher or principal.
