In most cases, vomiting is caused by gastrointestinal dysfunction, which may result in accelerated intestinal peristalsis and the immaturity of the baby’s digestive system, making it easy for the baby to vomit. If the baby still has the desire to eat milk after more than half an hour of vomiting, he or she can nurse again. Babies with immature gastrointestinal functions have a very high probability of vomiting, so nursing again immediately may cause vomiting again and increase the burden on the gastrointestinal tract. Usually, if the baby has the desire to eat milk after half an hour or more, you can consider feeding again. If the baby has repeated vomiting, accompanied by diarrhea, fever and other symptoms, and is in a poor mental state, nursing should be suspended and the cause of vomiting should be clarified at the pediatric department of the hospital if necessary. In addition, the baby should be kept on his or her side after spitting up and the vomit in the mouth should be cleaned to avoid accidental aspiration. At the same time, after the next feeding, do not put the baby down immediately. It is recommended to hold the baby upright for a while to let him/her digest the food and put him/her down again after burping.
