In infants an allergy to cow's milk is quite common. Around 1 in 50 infants are allergic to cow's milk, with most children growing out of this allergy by age 4.
How do I know my child has allergy to cow's milk
Up to 2 hours after consuming a small amount of cow's milk, even a small amount your child may experience symptoms such as hives, eczema, vomiting or diarrhoea, noisy breathing, wheezing or swelling in the face, Babies may lose their muscle tone and become floppy (this is a severe reaction and requires urgent medical care)
Several hours post consumption of a moderate amount of cow's milk a baby may develop vomiting, diarrhoea, blotchiness or notable skin redness.
After a large amount of cow's milk a baby may still develop symptoms so don't discredit the milk as the problem if it has been a couple of days since consumption.
How can I get my child's cows milk allergy diagnosed?
If an immediate response occurs, diagnosis is usually obvious and your GP should arrange for skin prick tests or blood specific IgE tests,
If response is much later, a referral to an immunology specialist may be required
NOTE:- tests such as the Vega test, kinesiology testing, Alcat or allergy elimination tests or IgG tests are not proven to be reliable. The IgG test will confirm that you have been exposed to a food, but not that you have any type of allergy to it.
