When spitting up occurs in an infant, parents need not overstress. The first step is to take prompt measures to tilt the child’s head to the side when vomiting occurs while the child is lying down. Vomit can easily lead to neonatal asphyxia when it accidentally enters the trachea, so try to keep the upper body elevated when the infant is in the lying position. After the baby has finished eating milk, you can hold it vertically and gently pat the child’s back to help the child swallow the milk quickly, this method can also help to eliminate the air in the stomach esophagus, also known as “burping”; secondly, it is recommended that the mother control the amount of milk the baby eats, do not eat too much; then again, pay attention to abdominal warmth to avoid The baby’s digestive function will be affected by the cold, causing vomiting. The doctor will determine whether the vomiting is caused by disease and choose the appropriate auxiliary tests, such as abdominal ultrasound for suspected congenital hypertrophic pyloric stenosis and gastrointestinal imaging for suspected digestive tract development problems. In addition, when feeding, let the baby rest for a while to facilitate breathing; when bottle-feeding, the size of the milk hole should be moderate, and when spitting up occurs, deal with it in time to prevent choking.
