Burping in infants can continue beyond 4 months of age, but this time is not an absolute limit and can be adjusted according to the developmental characteristics of each child, partially extending up to 6 months of age. The newborn’s stomach is not well developed, the pylorus and cardia are immature, and the stomach is transverse for up to 3 months, and the stomach is basically formed by 4-6 months of age, so burping must be done after feeding. The main purpose of burping is to empty the air from the stomach to prevent spitting up. To burp, hold the baby upright with the head tilted to the side and gently punch the back with your hand in a hollow shape to expel the gas from the stomach. Usually, burping is no longer necessary after 4-6 months of age, but a small number of feedings should still be used. In addition, it is recommended that parents develop a good eating routine for their children and avoid cold in the abdomen to effectively prevent gastrointestinal disorders.
