Why does a baby always choke when drinking water from a bottle?

In general, infants choking while drinking water from a bottle may be caused by factors such as fast milk flow from the bottle, oral ulcers, gastroesophageal reflux, pneumonia, or cleft lip and palate. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a healthcare professional. Specific analyses are as follows:

1. Fast Flow from the Bottle

The nipple flow rate of the bottle may be inappropriate; an excessively fast flow can cause the infant to swallow too slowly, leading to choking. Symptoms generally improve gradually after switching to a suitable bottle.

2. Oral Ulcers

Oral ulcers are a common oral condition that causes sores and pain in the oral mucosa. When using a bottle to drink, infants may experience discomfort or pain due to the ulcers, making them more prone to choking. Usually, no specific treatment is required, and ulcers heal on their own within about a week.

3. Gastroesophageal Reflux

Poor feeding practices may lead to damage of the gastric and esophageal mucosa, resulting in gastroesophageal reflux, which allows stomach contents to easily flow back upward. This can typically be improved by feeding smaller amounts more frequently and burping the baby promptly after drinking.

4. Pneumonia

Choking may also result from lung infections caused by pathogens such as *Klebsiella*, *Escherichia coli*, or *Chlamydia*, leading to pneumonia and impaired digestive function. Treatment usually depends on the type of pathogen and should follow medical advice regarding medication.

5. Cleft Lip and Palate

Infants with cleft lip and palate have structural abnormalities in the mouth and airway, impairing their ability to control milk flow, which makes it easier for liquid to enter the airway and cause choking. Special attention should be paid to feeding techniques and positioning to reduce the risk of choking.

It is recommended to closely observe the specific situation. If the infant frequently chokes or has other feeding difficulties, a hospital visit is advised for relevant examinations and appropriate treatments based on the results.
