Is it possible to have one of the most disgusting autistic events and a great day of progress at the same time?
Yes. Yes, it is.
Poop. I could go into a lot of disgusting detail, but I'll spare you. I will say these words and you can use your imagination: spoonfuls, mold, mysterious smells, trampoline netting, smears, rotating fan, Jacob. Have fun with that.
And now for the good stuff because I'd like to get the occurrences of the last few hours out of my mind. However I doubt I will ever forget. It's seared there forever.

Poop.
When you have a child on the spectrum, poop takes on a whole other meaning. Does your child poop? How often does he poop? What makes him poop? What does his poop look like? What is the typical shape of his poop? How large are his poops? Does he poop more than once a day? Where does he poop? What is the makeup of his poop? Is his poop solid?
