Baby with allergy refuse to eat.

It’s fun to introduce new foods to your baby. However, experimenting can be scary if your baby suddenly exhibits an allergic reaction. Whenever you give your baby something new to try, keep in mind the following warning signs of a food allergy.

Allergic Reactions to Look Out For

As you introduce new foods to your baby, be on the lookout for any allergic reactions. You’ll notice quick changes and symptoms in different areas of the body, like the:


If your baby is having an allergic reaction to a newly introduced food, you may notice skin issues including:

  • Redness
  • Swelling beneath the surface of the skin
  • Hives
  • Bumpy textures
  • Itching and scratching


Your baby’s eyes could show a reaction to a food allergy. Be aware of problems like:

  • Itchy eyes
  • Excessive tearing
  • Redness on the skin around the eyes
  • Swelling around the eyes

Respiratory System

If your baby has a food allergy, they could develop issues in their respiratory system. Indicators include:

  • Wheezing
  • Difficulty breathing
  • Excessive coughing
  • Hoarse voice
  • Excessive sneezing
  • Nasal congestion and runniness


The mouth is commonly affected by a food allergy. Pay attention to issues involving your baby’s mouth like:

  • Swelling of the tongue, lips, and palate
  • Itchiness on the inside and outside of the mouth


Sometimes an allergic reaction to food can trigger problems in your baby’s digestive system. Be aware of specific symptoms like:

  • Stomach pains
  • Reflux
  • Nausea
  • Vomiting
  • Diarrhea

Please note: if your child has a food intolerance, they will also exhibit similar problems with their stomach. Proper testing can help you determine if your child has a food allergy or food intolerance.


Food allergies can trigger reactions in your baby’s heart and blood circulation, resulting in:

  • Racing heartbeat
  • Decreased blood pressure
  • Dizziness and fainting
  • Loss of consciousness

If you suspect your child is allergic to a new food, assess their symptoms. Sometimes an oral antihistamine (Benadryl for example) will calm the reaction. However, take immediate action if their allergies progress beyond a mild response. Pay attention to warning signs like a rapid heartbeat, trouble breathing, or difficulty swallowing. Call 911 if these symptoms develop.
