Tonight during his bath, Lucas said he had to go poop. Up until tonight, he's been reluctant to sit on the toilet for poop, asking for a diaper instead which we give him, based on advice from our pediatrician.
So I asked if he wanted to sit on the toilet and he said yes.
As he sat there, for more than a 1/2 hour, I told him poop-centric stories and we talked about the poop process. I told him, "You just have to push it out and it will all be just fine."
I'm not sure where Lucas heard the analogy, but he thought about the pushing and said, "It's kind of like pushing out a baby."
