My oldest son turned two in November. The "BIL" is almost done PTing his almost three year old son, and is pushing for PTing my son. The boyfriend is pushing the other way, saying that he's not ready. In the morning, I try to put him on the pot, but it doesn't go anywhere from there. I can sit in there forever, and he won't do anything. He'll sometimes push to try to poop, but ends up crying, as if it hurts. I bought Yogos, which are his favorite treat, and are ONLY given to him while he's on the pot. What am I doing wrong?
