Milk allergies are often confused with lactose intolerance, but they are distinct conditions. A milk allergy involves an immune response to the proteins in cow's milk, whereas lactose intolerance is a digestive issue. Milk allergies can cause symptoms ranging from skin rashes to gastrointestinal distress and respiratory problems. For children with milk allergies, avoiding dairy products is crucial, which can be challenging given their prevalence in everyday foods. Parents need to be vigilant about checking ingredient lists and finding suitable substitutes to ensure their child receives adequate nutrition without exposure to allergens.

Egg allergies are common in young children and can be particularly challenging due to eggs' widespread use in cooking and baking. Reactions can occur from consumption or even inhalation of airborne particles during cooking. Many vaccines are also cultured in egg-based mediums, posing additional concerns for allergic children. However, some children outgrow egg allergies as they age, allowing for reintroduction under medical supervision. Parents must be aware of hidden sources of eggs in processed foods and be prepared to offer egg-free alternatives to ensure their child's safety and nutritional needs are met.
