Amity: Faelan, do you need to use the potty?
Faelan: Bathroom!
He grabs a duster and runs to the bathroom. I take off his diaper and he sits on the potty chair, then picks up the duster and pushes it around on the floor, sweeping up a bunch of toast crumbs. Don't ask me why the bathroom floor is covered in crumbs.
Amity: What are you doing?
Faelan: Duster! Cleaning!
There is a pause while he pees, then points to the floor in front of the potty chair.
Faelan: Pee down there. Clean it.
He swabs the duster around in front of the chair.
Not very hygenic, but definitely communicative!
