We had quite the regression with pooping in the potty. Week 1 was a struggle, but by week 2 he was NAILING it. He was having successes everyday for 5 days in a row!!! I was so proud, I thought we were in the clear, he was getting it!!!! Then, one terrible Friday, he started holding it. He was starting to act all scared again to go in the potty, and it was an ALL day thing. I kept thinking anytime now he'd just do it. I swear we "tried" on the potty at least 100 times that day. Well, finally at the end of the day, the poo came out, all be it not in the potty. Turns out he was terribly constipated (again) and it was hurting him. Despite his altered diet to keep his stool soft. Poor guy. Since then he's been holding it and pooping in his pull-ups at nap time or sometime before I get him in the morning. I've decided to take a few weeks break, and try again. I talked to a nurse the other day who advised the same and had a few good tips. I'm continuing to alter his diet to keep his stool soft, I'm just hoping this doesn't last too long. But I try to remind myself he's doing great for his age, he's totally got the pee thing down, and it helps to know that this is actually a very normal problem with toddlers and potty training. So we'll keep trying. I know he can do it!
