Why does my baby always cough and choke when drinking formula milk? What should I do?

Infants often cough and choke when drinking formula, which may be caused by factors such as an overly large nipple hole, improper feeding posture, congenital tracheal stenosis, gastroesophageal reflux disease (GERD), or respiratory tract infections. Solutions include adjusting the flow rate of the bottle, correcting feeding posture, and considering surgical or pharmacological treatments depending on the situation. A detailed analysis is as follows:

1. Overly large nipple hole: If the hole in the bottle nipple is too large, the milk may flow too quickly for the infant to swallow properly, leading to choking and coughing. Adjust the size of the nipple hole so that when the bottle is inverted, the milk drips out drop by drop rather than in a continuous stream.

2. Improper feeding posture: Incorrect feeding positions, such as laying the infant flat or having the head too low, can cause milk regurgitation and increase the risk of choking. It is recommended to correct the feeding posture by slightly elevating the infant's head and positioning the body at a 45-degree incline to reduce the risk of choking on milk.

3. Congenital tracheal stenosis: Congenital tracheal stenosis is an obstructive airway condition present at birth, which may be caused by various factors such as genetics, infections, or injuries. The narrowed area is prone to blockage by milk, causing choking and coughing. The primary treatment for congenital tracheal stenosis involves surgical interventions such as balloon dilation under bronchoscopy or stent placement.

4. Gastroesophageal reflux disease (GERD): During reflux episodes, stomach acid and food may irritate the esophageal mucosa, triggering a cough reflex and resulting in choking while drinking milk. This may be accompanied by symptoms such as infant irritability, difficulty falling asleep, and belching. Maintain regular eating habits and avoid overeating or eating too much. When sleeping, elevate the head of the bed by 15-20 degrees to reduce reflux.

5. Respiratory tract infection: When infants have respiratory infections, increased secretions in the airways may interfere with swallowing, making choking on milk more likely. Take the infant to see a doctor promptly, and use auscultation and other diagnostic tests to determine if a respiratory infection is present. If necessary, follow medical advice to use medications such as oral liquid of Shuanghuanglian, Vitamin C Yinqiao tablets, or children's lung-clearing pills. Additionally, ensure good indoor air circulation to prevent cross-infection.

After feeding, it is recommended to clean the bottle promptly and maintain the hygiene of the bottle and nipple to prevent bacterial growth.
