L.D.
I've got the same problem with my 2 1/2 year old daughter. She's been potty training for almost 2 months now and doing pretty well with peeing and was making progress with pooping unil a month ago when she suddnely started refusing to poop and seems to dislike the "mess" it makes. I can't get her to understand that its "messier" in her underpants or pull-ups than it is in the potty but she doesn't seem to get it. I'm frustrated like you. Have you made any progress?
