Babies and food allergies

Baby food allergies

Babies are more likely to have an allergy if there is a history of asthma, eczema or hayfever in the family. A food allergy typically causes an immediate reaction after eating the food – usually seconds or minutes after eating it. Typical symptoms are:

  • Itchy skin (hives or rash)
  • Itchy and/or swelling tongue and lips
  • Sneezing
  • Blocked or runny nose
  • Shortness of breath
  • Coughing
  • Vomiting

More severe allergy symptoms are the same as above and/or:

  • Tightening of the throat
  • Difficulty breathing
  • Feeling faint
  • Pale and clammy appearance

The most common food allergies are:

  • Citrus fruits (e.g. oranges), Seed fruits (strawberries) and Kiwi fruit
  • Cow’s milk
  • Eggs
  • Fish and shellfish
  • Nuts
  • Seeds
  • Soya
  • Tomatoes
  • Wheat

A food intolerance has a more delayed reaction, which may not manifest until hours or days after eating. The most common effects of food intolerances are:

  • Stomach pain or colic
  • Bloating
  • Wind
  • Diarrhoea and occasionally vomiting

The most common food intolerances are the same as for allergies. Introduce these foods after your child has reached six months, and try them one at a time monitoring your child very closely to check for a reaction of any sort, in which case you should consult your GP or if it’s a very severe reaction (such as difficulty breathing or any swelling occurs) take your baby to the local Accident and Emergency department.
