Hiccups are a common symptom in infants. For example, when an infant eats milk too quickly or inhales cold air, the plant nerves are stimulated and the diaphragm suddenly contracts, causing rapid inhalation and a “hiccup” sound, which is called hiccups when the sound is made rhythmically. Parents should help their infants burp in time to get the gas out. In addition, burping has a calming effect on the baby’s emotions. If the burp doesn’t come out after a few minutes, don’t worry too much, just keep feeding because babies don’t always burp. Try burping again when he is full, and then hold him upright for 10-15 minutes to prevent spitting up. Babies who are on formula should be burped at least every 3-5 minutes during feedings.
