A comprehensive assessment is made on the basis of the duration of spitting up and the performance of the baby after spitting up, as well as the general condition of the baby. If the baby’s vomiting phenomenon is not very obvious, the number of times per day, the baby’s physical growth and development is normal, most of them are because of the incorrect breastfeeding position, or the baby sucking the nipple when inhaling too much air, resulting in excessive air content in the stomach, easy to vomit phenomenon. So pay attention to the correct breastfeeding position, hold the baby upright after feeding, and lay him/her flat after burping. If vomiting occurs around 20 days after birth and the vomiting occurs after every feeding, pay attention to the possibility of congenital pyloric hypertrophy and stenosis. Babies after vomiting hunger is obvious, but physical growth and development is backward, poor nutrition, we should promptly go to the hospital, given to do abdominal ultrasound to clarify, if necessary, surgical treatment.
