A 5-year-old girl has visited the hospital many times with no significant improvement. What should be done when a baby frequently vomits? Due to the characteristics of a newborn’s digestive system, vomiting in newborns is a normal phenomenon. Do not feed the baby too much milk at once, and do not feed too frequently. When feeding the baby, hold the baby upright, and after feeding, hold the baby vertically against your shoulder and gently pat the baby’s back to expel the air swallowed into the stomach. Different causes lead to different symptoms, and patients need to undergo systematic and standardized examinations at regular three-level A hospitals for symptomatic treatment. In addition, patients should maintain regular daily routines, take good cold prevention and warmth measures, eat light and soft food, ensure good ventilation, and drink plenty of hot water.
