Dairy is a common allergy in infants and toddlers. About 2.5% of children under age 3 are diagnosed with a dairy allergy.
Most children who develop a dairy allergy will eventually outgrow it. Common symptoms are a stuffy nose, skin rashes, hives, eczema, blood in stools, asthma, and in rare instances, anaphylaxis.
A dairy intolerance is much different than an allergy and is caused when the child is missing an important digestive enzyme that can break down the sugar or the proteins in the milk.
Lactose intolerance is the most common type and about 30% of the population has it. Lactose is the sugar found in milk and when the body can’t break it down it will cause gassiness, bloating, and stomach cramps. This is the most common food intolerance and is lifelong and will only worsen as the child grows and ages.
Casein intolerance has similar symptoms but it is much harder to manage. Casein is the protein found in dairy products and it is used as a filler in many processed products on the shelves in stores. An intolerance to casein will not show up on an allergy test so the only way to discover it is through an elimination diet. And foods labeled dairy free often have casein in them as an ingredient.
