Infants who have been frequently straining hard to poop are mostly considered to be caused by constipation, which can be dealt with through medication and dietary changes. 1. Medication: After the diagnosis of constipation, if the child has not defecated for a long time, resulting in abdominal distension and other symptoms, you can use medication such as Keserol to promote defecation with the permission and guidance of the doctor, and you can also supplement some intestinal probiotics to help the child’s intestinal peristalsis and promote normal defecation. 2. Change the dietary structure: you can give the child some fiber-rich food, such as vegetable puree, fruit puree, etc., and ensure that hydration, to avoid the lack of dietary fiber or lack of water caused by the lack of bowel movement. Parents should train the child to defecate on time every day to help the child to form a bowel reflex, and can also gently help the child to rub the abdomen to help improve the child’s digestive ability.
