My son had the same difficulty. He was pee-trained for 4 months before being poop trained. What finally worked for him was to break it into stages that he could successfully manage. 1st stage, poop (in diaper ... he was normally in undies at this point, but I'd put him in a diaper to poop) in the bathroom, any position he wanted. 2nd stage, poop (in diaper) sitting down in the bathroom (he chose the floor). 3rd stage, poop (in diaper) sitting on the potty. 4th stage, poop in the potty. We stayed at eat stage until it was comfortably mastered. He also got small rewards (a small candy) for doing it according to the correct stage. Stage 1 was easy. Stage 2 and 3 were harder, but since he felt like he could do it, he was really motivated, and worked on it. Stage 4 was simple, because he had gained the confidence he needed when the diaper was still on. Also, definitely load up on the fiber, at least while training. You want the bowel movements to be fairly soft (and nonpainful). Good luck!
