Regression with Potty Training

I'm not sure if this will help, but here goes. My son would poop in the potty no problem, then all of the sudden he was going in his pull up at nap, and then again right before he woke up. I knew he could poop in the potty, I think he was just lazy and or testing what would happen. What I did was pay close attention to when he went. I figured out his pooping schedule. I msde sure he tried the potty during those particular times and read him 3 stories to keep him there for a bit. He almost always did it. On days when he didn't I watched him like a hawk. I never let him hide when I knew he wanted to. I found if I asked him does he need to go, he always said no. Instead I said "you want mommy to take you to the potty" He either saud yes or ran. Also he was making tiny poop and then pooping again later. To deal with this I awarded him for making what we call "rainbow poopy" not baby poopy. I rewarded him by wrapping up old matchbox cars that he forgot about and giving them as a present. It all worked just took timeeeeee. Now he is telling me when he has to go and or just running to the potty most of the time without reminders. If you listen to any of my advice, listen to this " Watch her like a HAWK." Don't let her hide to poop! You may need to neglect yourself and your house for a couple of days to get her back on track, but its worth it. Hope I helped.

We has this issue with our son.
We read a recommendation and tried it with success.
For 2 weeks straight we kept him bottomless (he only wore a shirt) around the house. When he had to go we rushed him to the potty and cheered when he "produced".
It worked!
Good Luck!

A., have you tried making her clean herself up? Also we would throw the panties or undies away, this would make my kids feel said since they were usually thier favorite characters.
