No way! No time-outs for accidents. She is just not ready yet. It will come in time when she is ready. Kids have a natural fear of pooping in the potty. Also, for years they have been used to pooping while standing up, and all of a sudden they have to learn how to do it while sitting and having water splash up on their bottom. No wonder it takes kids longer to poop in the potty. When you put them in time-out for pooping in their panties, they learn "well, I just won't poop at all" and then constipation becomes a real problem. Good luck!
