Infant flatulence can usually be improved after 4-5 months of age, when the gastrointestinal function of infants is gradually improved and the intestinal flora is stabilized. Infant flatulence is usually caused by excessive fermentation of sugar in the infant’s underdeveloped gastrointestinal tract due to the excessive amount of sugar in the breast milk or formula that the infant consumes, resulting in excessive gas production. In addition, excessive involuntary swallowing of air by infants may also be the cause of intestinal flatulence. Therefore, limiting the mother’s sugar intake and burping the infant after each feeding can be effective in preventing or reducing flatulence. As infants grow older, generally around 4-5 months of age, their gastrointestinal function can be relatively well developed, and the phenomenon of intestinal flatulence can be significantly relieved. In addition, the appropriate clockwise direction for the infant abdominal massage, can promote intestinal peristalsis, exhaust, thereby reducing the infant gastrointestinal discomfort. However, it should be noted that if the infant’s abdomen is significantly inflated and accompanied by pressure pain, it is recommended to seek medical attention in a timely manner to identify the cause and then actively treat it.
