Milk allergy most often appears before a child's first birthday. Almost all cases present before one year of age.
While milk allergies can develop at any age, they are most commonly diagnosed in infancy. The early onset is highlighted by numerous sources, including the observation that "almost all cases present before one year of age." Cow's milk allergy is one of the most common presentations of food allergy in early childhood. Almost all cases present before one year of age. This means that while adults can develop milk allergies, it's significantly less common than in infants and young children.
Understanding the Timing of Milk Allergy Onset
Several factors contribute to the prevalence of milk allergies in early childhood:
- Introduction of Cow's Milk: Infants are often introduced to cow's milk or milk-containing products early in their lives, increasing the chance of an allergic reaction.
- Immature Immune System: A baby's immune system is still developing, making them more susceptible to misidentifying harmless proteins, like those in cow's milk, as threats.
- Genetic Predisposition: A family history of allergies can increase the likelihood of developing a milk allergy.
