My son is 2 and for the past year he's had issues with being afraid to make a bm. And he isn't potty trained and this didn't come from an attempt to potty train. He just seemed to decide it was unpleasant, either gross or painful, and started holding it. We talked to the pediatrician, we gave him diabetic candy, laxatives, fiber gummies - and he generally eats a good diet for pooing. (He loves black beans.) The problem isn't consistency, it's that he just doesn't push it out when the urge hits him. For the past month and a half, I've been charting him. He poos now twice a week, and without discomfort, although he still does quite a little dance and gets upset. When we first gave him the fiber gummies, he went almost every day for a week, but then went back to his old routine. I'm figuring as long as he goes twice a week and isn't uncomfortable, that's ok, but I'd feel better if he went more often.
