When infants catch a cold, it is mostly due to a viral infection, which reduces their intestinal digestive function and increases their intestinal sensitivity. Therefore, it is not advisable for them to eat eggs during this time. Firstly, eggs are one of the most common allergens for children, and their sensitivity increases during a cold, possibly triggering allergic symptoms in babies, including gastrointestinal symptoms, exacerbation of skin symptoms, and even respiratory symptoms. Secondly, eggs contain a relatively high amount of fat, which, if consumed during a cold, might cause the baby to experience vomiting, nausea, abdominal pain, and diarrhea. Therefore, there is a certain risk involved, and caution is necessary.
