Babies with cold stomach can have symptoms of abdominal pain, vomiting, nausea or diarrhea and fever. If the baby does not have a fever and simply shows vomiting or abdominal pain is very mild and there is no diarrhea, you can pay attention to heat preservation, eat a light diet, eat some thin rice porridge and noodles, and drink more water appropriately. When vomiting is strong, you need to fast for 4-6 hours, but you don’t need to fast from water, you can drink water in small amounts several times. If the child is in good spirits, you can take some digestive medicine to observe, and at the same time you can use a warm umbilical cord patch, or a clove appetizer patch to help the child digest. If the child has fever, vomiting more frequently, or diarrhea, especially if the body temperature repeatedly exceeds 38 degrees, and the mental state is not good, it is recommended to go to the pediatrician for an interview.
