Why does a 2-year-old child vomit at night after drinking milk before bedtime?

It may be caused by the child drinking too much milk at night. Consuming excessive milk in the evening can overload the stomach, leading to vomiting during the night. To prevent this, parents should offer the child light foods before bedtime, such as fruits, vegetables, and bread, rather than allowing excessive milk intake. Additionally, parents should try to avoid giving the child too much water at night to prevent vomiting due to excess fluid. It is also advisable to avoid overfeeding the child in the evening to reduce the digestive burden during nighttime. Parents should ensure the child rests quietly before going to bed, which can effectively reduce episodes of nighttime vomiting. If discomfort persists, prompt medical attention is recommended.
