My son is 3 1/2 years old, and in preschool. And I'm hoping he doesn't need to ever go poop at school, because he will ask for a pull up, when it's time to poop. Our pediatrician suggested doing a pull up countdown 'til it's time to poop in the toilet. I tried that this summer, and I gave in, because he would hold his poop, and I don't want him to get backed up. He will NOT poop on the toilet. He's pooped on the toilet twice already, once when he turned 2, and another time during x-mas time. But, I think the time he pooped during x-mas traumatized him, because as he was pooping, he kept yelling out, "my butt hurts, my butt hurts!" I guess I can try the pull up count down again, since I just bought a whole box the other day. Any suggestions how I can help his fear of pooping in the toilet?? I'm hoping he sees his classmates poop on the toilet at school, and will eventually do the same. For now, he waits to poop when he gets home, since he knows we have pull ups at home.
