Fix the constipation: A person with constipation needs to be sure there is no other disease causing it. If constipation is just due to slow movement of the food and poop through the gut, some things to try include: vegetables, prune juice, prunes, Miralax, senna syrup, milk of magnesia, other pediatric laxatives... Can see the pediatrician often, until problem is solved, to avoid interfering with his potty training.
