Infants are more prone to gastrointestinal flatulence, mostly physiological, which may be related to the predominance of abdominal breathing in newborns and the dysfunction of the gastrointestinal tract. Infants swallowing too much gas while crying or breastfeeding can also lead to flatulence. If the child has no other symptoms or discomfort, and if it does not affect growth and development, it can be relieved by paying more attention when breastfeeding and burping promptly after feeding. It can also be pathological, such as an infection that causes disruption of the gastrointestinal flora. If it is pathological, there are usually other symptoms that parents should be aware of to identify.
