There may be physiologic and pathologic reasons for babies choking on milk. For physiological factors can be adjusted feeding posture, for pathological factors need to be examined to determine the cause of the disease for symptomatic treatment or surgical treatment. 1. Physiological factors: As the epiglottis of infants is not yet mature, the lower esophageal sphincter is flaccid, the cough reflex is weak, especially in preterm infants with an underdeveloped gag reflex, choking is easy to occur when feeding is too fast and too urgent, inappropriate posture, or lying down after feeding. It is recommended to adjust the feeding posture, the beginning of the nipple should not be too big and the angle of tilt of the bottle should be slightly smaller when bottle feeding, and keep the head high and the feet low. 2. Pathological factors: congenital developmental malformations such as tracheoesophageal fistula, laryngeal cartilage dysplasia, cleft palate and other congenital developmental anomalies require surgical treatment; non-physiological gastro-esophageal reflux needs to be treated with thickened formula, special positions and frequent patting, and close observation. If you keep choking on milk, it is recommended that you consult a regular hospital in time and cooperate with the doctor to improve the examination and identify the cause.
