Time-out for Caroline, but the joke's on me

So today, Caroline kicked me while I was changing her diaper. I don't tolerate kicking so I whisked her right off to "bad girl corner" (our version of time-out). Since we were mid-diaper change, she was diaperless, but she knows how to hold it after a bath, so I didn't worry about it. I left the room and after about 2 minutes, I heard her say "I'm ready to be a good girl. " I went in to get her and she continued with "I went tinkle." "Perfect", I think. She tinkled all down her leg, her pants, and all over her socks. Lovely. I guess maybe I'll make sure the diaper is on first before I time-out her again for diaper changing kicks.
