If your child has failed to have bowel movements for many days, he must be in pain. In such a situation, you might want to resort to artificial medicines to stimulate his bowel movements. You can administer enema but only after consulting with a doctor. The enema should be administered at night so that it ends up lubricating the area around the rectum and makes the process of passing stools easier. Ideally, coconut oil should be used for enema as it triggers the intestines and stimulates the bowel movement. But enema should be used as a last resort and only after consulting with a doctor. Do NOT try to administer enema to your child on your own and without supervision.
