The reasons why babies vomit after eating milk are as follows: 1. It may be caused by indigestion and bloating, or it may be caused by inflammation of the intestinal tract caused by bacterial or viral infection, resulting in vomiting caused by poor gastrointestinal digestion. Regardless of the cause of vomiting, control the child’s diet and try not to feed within 1-2 hours after vomiting to avoid vomiting again after eating milk and causing gastrointestinal stimulation. You can give oral medication to help gastrointestinal digestion, such as Gastrointestinal Oral Liquid, Mamma’s Aid, etc. to adjust the gastrointestinal function. If the baby can eat supplemental food, oral rice flour and porridge can be given to adjust the stomach and intestines. If the baby has not eaten complementary food, again oral milk must be fed in small amounts. 2, caused by surgical diseases, such as intestinal obstruction or intussusception caused by vomiting after eating milk, the child vomiting symptoms are heavy, the mental state is not very good, you need to actively take the child to the hospital for detailed examination after further treatment.
