Why does a two-month-old baby who is breastfed always vomit?

Patient's question:

No

Doctor's answer:

Hello, because the baby's stomach is in a horizontal position and has a small capacity, the cardia connecting the esophagus is relatively wide and has poor closing function, while the pylorus connecting the small intestine is relatively tight. When the baby feeds, they often inhale air, making it easy for milk to reflux into the oral cavity, causing vomiting. By the time the baby is 4-6 months old, the vomiting will decrease.
