Babies often suddenly spit up the milk they eat, if the amount is not much, it is generally called “overflow”; if the amount of milk or the speed is fast, or even ejected, it is called “spitting up”. If a newborn vomits frequently, parents should pay attention to the following points: 1. Pay attention to whether the disease is caused by frequent vomiting, frequent infectious diseases in newborns, including respiratory, digestive tract and other parts of the infection may cause frequent vomiting, some will be accompanied by poor response, diarrhea, fever, etc., need to be judged according to the child’s performance; then pay attention to whether there are problems with the development of the digestive tract, such as congenital hypertrophic pyloric stenosis, generally It will also show frequent vomiting and unsatisfactory weight gain, which can be diagnosed clearly through imaging examination. 2, the newborn’s digestive system is not mature, especially in the cold, feeding when it will further affect the digestive function, causing frequent vomiting, this situation should be fed more carefully, after feeding, pay attention to the baby pat back, half an hour after feeding, it is best to keep the baby in an upright position. Don’t shake your baby within half an hour after feeding, and don’t let your baby cry violently or get too excited. If bottle feeding, pay attention to the teat being filled with milk to avoid inhaling too much air, the size of the teat hole should be moderate and the temperature of the milk should be appropriate. Pay attention to your abdomen not to get cold. 3. Prevent milk from being accidentally inhaled into the trachea: Since the opening of the esophagus and the opening of the trachea are connected in the throat, pay attention to preventing milk from entering the trachea when spitting up, i.e. choking. (1) If vomiting occurs while lying down, quickly turn the baby’s head to the side to avoid vomit from flowing into the throat and trachea. (2) If you find that your baby is breathing faster and not breathing smoothly, you need to send him/her to the hospital for treatment in time.
