Save a diaper, use the tub

Elise got her second bath in the tub tonight -- we still use the sink for quick, drive-thru baths -- but it was the first one I was involved with.
Everything was going swimmingly -- until someone had a bowel movement in her bath chair. I told Anni that we're definitely parents now when we have an exchange like this:
"There's crap all over the bathtub," I said while cleaning the tub.
"Well, it's one less diaper to change," she said.
