"Mom pee," she observed. And when I didn't respond she repeated herself. "Mom pee! MOM PEE!"
Finally I gave in. Just as she likes us to say aloud the words she signs, she likes to have her words repeated back to her. "That's right. Mom's going to the bathroom."
"Mom pee! Yeah!" She exclaimed one more time. And then as I zipped up my jeans, she waved to the flushing toilet. "Mom! Pee! Bye-bye!"
The people waiting in line smiled at us as we emerged from the stall.
