We are there as well, and I actually expected it. My daughter has pooped in the potty several times, but then goes back to the diaper. I am the same way with putting the diapers just so she will poop cause I don't want her hurting and know eventually it will happen. What I have done when she does poop is: Set a stool in front of the potty for her to put her feet on. It's harder to poop with your feet dangling (we adults don't even do that). If you notice many squat when they poop, so you want something that bends her knees up so its easier for her). Also, if she mentions pooping and then says never mind, I take her panties off and let her run around naked but remind her where the potty is. Every time she has done it is when I wasn't watching her and she had alone time (this obviously will depend on your child). Also talk about how cool it is to see the poop swirl down the toilet..lol. My sister had the same problem with her son and it took one time with grandma putting him on the toilet (she saw his face and put him on it real quick). So sometimes it takes someone else to be there instead of mom for that initial time.
