My mistake.

Yesterday Eva whipped off all her clothes (a commonplace event) and jumped up and down on her bed—an activity with potentially hazardous results for a child not yet potty-trained. “It’ll be OK,” I assured myself. “Even a hamster won’t pee in the same corner of the cage he sleeps in.”

As day turned into night we cuddled up for her bedtime story, and I discovered toddlers are nothing like hamsters.
