I need help, my 7 yr old son has had by problems since he was 3, he has been to drs and done miralax for years. He holds his poop in all the time. I always worry it might be something else, but living on miralax every day is not an a good idea in my opinion. His problem is all in his head, and we've just recently gone to enemas every 5 days when there's a problem. Used to be 10 days. That was scary. He will literally hold it until you make it come out. I've tried punishments rewards etc to no avail. We've used magnesium citrate, fiber supplements, suppositories and prunes. It all helps for a while then right back to holding it. Any ideas would be great, something I haven't thought of? Also he eats a good diet, veggies fruits wheat bread lots of water, gets plenty of exercise. Just lost.
