Ok, this reminds me of a potty training story from DS#2.
For him, going #2 was harder to do in the toilet.
Each child is different.
We were at a rest stop somewhere in Tennessee, Smokey Mountains,
and we all go to the bathroom.
DS's turn to take little Joseph, age 2.
DS gets him up on the toilet, his face turns red, "Move-a-bowels!"
(I didn't make-up this phrase, he did.)
He let everyone know he had done it in the toilet.
"Move-a-bowels!" he exclaimed very proudly.
DS gets him cleaned up, washing hands at the sink.
Joseph's face turns red again, louder: "Move-a-bowels!"
He grunts loudly for the effect.
(Must get this from his Dad, not from me!

!)
They both quickly return to the stall, for more BM.
"Move-a-bowels!" he again exclaimed very, very proudly.
A few snickers from the others in the men's room.
DS gets him cleaned up, washing hands at the sink.
3rd time, Joseph's face turns red, even louder for the entire bathroom
to hear him: "Move-a-bowels!"
Back in the stall for a 3rd time.
More loud grunting noises.
Everyone in the men's room was laughing at this little guy!
So cute!
They come running out of the men's room towards me:
"Me, move-a-bowels, Mom!"
The joys of being a parent!
