Infant spitting up like a fountain is usually normal and does not require special treatment if it is only episodic. After birth, the baby’s stomach is not fully developed and is in a horizontal position with a relatively small capacity. A variety of factors such as too much feeding and incorrect feeding position can cause the baby to spit up. In this case, parents can reduce the amount of milk feeding or pat the baby’s back after feeding in order to have some relief. If the baby spits up and loses weight rapidly, or coughs while vomiting, and the vomit is brown or green in color and sprayed, it is likely to be caused by gastrointestinal diseases or neurological diseases, and parents need to take the baby to the hospital for treatment. Parents should pay attention to control the amount of milk feeding, adjust the feeding posture and change the contaminated clothes in time after the baby vomits to avoid further stimulation to the baby.
