Question
My child was born 12 days ago, and they keep vomiting today. They used to be fine. What could be the reasons?
Answer
Vomiting is a common symptom of the digestive system, including vomiting and regurgitation. A small amount of milk returning to the mouth is considered regurgitation and usually does not affect growth and development, typically disappearing around 6 months after birth. Newborns are prone to vomiting due to their small stomach capacity, horizontal position, relaxed esophagus, and underdeveloped lower esophageal sphincter. The most common cause of vomiting is improper feeding, such as overfeeding, inappropriate milk temperature, and lying down immediately after feeding. Additionally, excessive early movement of the baby or violent crying may also cause vomiting. Mild vomiting and regurgitation usually have little impact on the body, but repeated vomiting may lead to electrolyte imbalance. It is recommended that parents closely observe and consult a doctor in a timely manner.
