It seems I pushed my luck a little too far. Just as I was proudly telling everyone how incredible Lily is at not peeing in the wrong places, I had a full on water slide in the aisle of the Rite Aid this morning. Luckily she was preoccupied while I search for and found first a foam matt and then a roll of paper towels to completely and responsibly clean up the situation.
I also paid for both items and calmly explained to Lily that we really need to pee ether in the potty or a diaper.
It was a great streak while it lasted.
