Vomiting in babies eating eggs may be caused by allergy, indigestion, and incorrect way of eating. 1. Allergy: the baby may be allergic to eggs, when eating eggs, because of an allergic reaction, which leads to vomiting, may also lead to diarrhea, abdominal pain and other symptoms. 2. Indigestion: Babies are still relatively small, gastrointestinal function is relatively weak, if you often give your baby eggs, it will easily lead to indigestion, which can cause vomiting, bloating and other symptoms. 3. Incorrect way of eating: If the baby eats too much at once when eating eggs, it may cause reflexive vomiting. If the baby eats eggs and vomits, parents should take the baby to the hospital in time to find out the cause and then target treatment.
