[Keely's Mommy]

Ok so here's my problem. Keely will go pee pee on the wee wee pad, but she will not poop on it unless its in her playpen. When I have her out in the living room she will pee on the wee wee pad, but poop near it and not on it. Does anyone know why she would do that? Is there some way of correcting this? Someone please help if you can.
