Poor little sweetie...I understand, I was the same way and I must tell it was because my parents always made a huge deal about "potty time" and I had anxiety every time I had to poop (but for me, it was not so much in my home, rather in other people's homes or in public places, school included). Handling bodily functions is such a delicate phase of a child's life and it's not less difficult for us parents...I know it's been difficult for me with my son. So don't beat yourself up, the previous poster gave you GREAT advice and resources, the doctor is makig sure her poop is soft, so you "just" need to find a way to teach her to "let herself go", to relax her body and mind, and take the pressure off of poop time. Good luck!!
