The method of exhausting gas in 2-year-old children usually needs to be decided on a case-by-case basis. For flatulence alone, techniques such as clockwise massage around the umbilicus can be used, or venting medications can be used to promote venting. You can also use drugs that reduce the production of intestinal gas, such as probiotics, to regulate the intestinal flora and reduce the production of intestinal gas. However, at the root, intestinal flatulence is caused by indigestion, so parents should invest more observation in reducing the occurrence of intestinal flatulence.
