The more I hear about potty problems and experience them in my own house the more I feel like we are pressuring our kids too much to figure out using the toilet right away. It took my son about 2 years after he was potty trained to poop in the potty on a consistent basis and even now he still has accidents (he is 5). It was so frustrating to be cleaning up his poop all the time that I would get really mad and punish him. It probably added to his anxiety about pooping in the potty. If I had to do it over again I would have relaxed and just reinforced that poop goes in the potty.
If you feel comfortable, let your daughter see you poop directly into the potty. It is hard to punish her when she thinks she is obeying you.
Gook luck and have patience, they figure it out eventually.
