Symptoms of milk protein allergy in babies

The gastrointestinal development of infants is still in the initial stage, and most infants cannot digest some common ingredients. Therefore, they can only feed on refined dairy products and other foods. However, some infants will show signs of intolerance to dairy products. For example, some infants develop symptoms of milk protein allergy after drinking milk. Let’s take a look at the symptoms of infant milk protein allergy.

The symptoms and signs of milk protein allergy are diverse, and the main symptoms are concentrated in three systems: the skin system, the digestive system and the respiratory system, as well as some general manifestations. Signs and symptoms of a cow's milk allergy can appear within two hours, several hours, or days after consuming milk, or they can appear immediately, within minutes. Symptoms of cow's milk protein allergy include:
