Most infant flatulence heals on its own. Infantile flatulence usually begins to appear 1-2 months after birth and gradually disappears 3-4 months after birth. Infants’ gastrointestinal function is not yet fully developed, and intestinal peristalsis is not yet as coordinated as in adults. In addition, when babies are in their mothers’ stomachs, their intestines are a sterile environment, while after birth they begin to eat breast milk and formula, at which time their intestines begin to come into contact with external bacteria. When the intestines break down the bacteria, more gas is produced inside the intestines, and therefore symptoms of flatulence may occur. Parents should help their infants to establish a better intestinal flora environment as soon as possible, so that probiotics can dominate in the intestines, so that the symptoms of flatulence will gradually improve. There are a number of treatment methods that can be taken when an infant develops intestinal flatulence. For formula-fed infants, when flatulence is more serious, you can consider changing the formula, and when choosing the formula, you can choose low-lactose, lactose-free formula or hypoallergenic formula. When bottle-feeding an infant, parents should pay attention to adjusting the nipple on the bottle at any time, and choose the right size nipple to avoid swallowing too much gas when feeding. If the infant is in a hurry to eat the milk, you can take the method of feeding in sections to avoid eating too much milk at one time and drinking a lot of gas, and to put the infant up to pat the back in between breaks. Especially for infants under three months old, we should pay attention to these situations when feeding, generally speaking, the intestinal flatulence of infants can gradually disappear in 3-4 months, if the intestinal flatulence of infants persists or aggravates, accompanied by other symptoms, you can go to the hospital for examination, to clarify the cause and treatment.
