In the case of milk spitting up in children, it may be due to the small capacity of the stomach and the horizontal position of the stomach, as well as the sound development of the pylorus of the stomach and the imperfect development of the cardia, so it is most likely to spit up when eating a lot of milk. Sometimes children swallow a lot of air into the stomach when they eat milk fast, thus causing vomiting. In this case, patting the child’s back after breastfeeding can gradually relieve the problem. If the child is still spitting up, stop feeding for 4-6 hours and do not give the child anything, including medicine, to avoid aggravating the spitting up symptoms. You can ask the doctor to check if the indigestion is caused by cold and then deal with it according to the test results.
