Hi M.!
My daughter (now 5) was the same way. She just refused to poop in the potty! We finally told her not to poop in her pullup, that she was a big girl now so she needed to tell us when she had to go (she pee'd in the potty all the time). Well one day (after she didn't poop for several days) she doubled over with a tummy ache. I asked her is she had to poop and she said yes. She was sweating and shaking so I told her it was okay if she pooped in her pullup (she really scared me!). Sure enough she had a HUGE BM!! I felt so bad b/c I felt like she held it b/c we told her she couldn't poop in her pullup anymore.
So, I eased up a bit about it. Soon she started telling me when she had to go! I'm not sure if it just finally clicked or if she got scared by the incident.
Just hang in there, I'm sure she'll come around
