Milk allergy in children occurs when a child’s immune system mistakenly perceives cow milk proteins as a threat and acts against them, triggering a reaction. A child allergic to milk develops symptoms when milk or milk-based foods are ingested. Depending on the severity of the allergic reaction, the symptoms may vary from mild to severe. Removing milk and milk products from the diet can help manage mild symptoms. In the US, milk allergy affects about 3% of children under three years (1). Fortunately, most children outgrow milk allergies before they turn 16. Thus, prompt treatment and management of the condition are essential for managing allergic reactions.
