Constipation in a 7-month-old baby can be relieved by drinking more water or supplementing with probiotics or using open plugs. When constipation occurs, parents can let their babies drink more water, which can moisten the intestinal tract to avoid excessive absorption of water in the stool, and also soften the stool in the intestinal tract, so it helps to help defecate. The appearance of constipation is related to the reduction of beneficial bacteria in the intestinal tract. Supplementing probiotics can improve the function of the intestinal tract and increase the beneficial bacteria in the intestinal tract, and the constipation phenomenon can be improved naturally after the intestinal tract function is restored. For babies with severe constipation, parents can inject the appropriate amount of corkage in the anal area to help stimulate rectal peristalsis and soften stools, thus relieving constipation. Babies with frequent constipation can often do exercises that can promote intestinal peristalsis to relieve constipation.
