Last night at 10, as Charming is known to do, he awoke fussing. I interpret this as, "I need to pee!" Primarily because he always goes and then settles down and goes back to sleep. So when he awoke fussy, I walked him down to the potty, stood him in front of it and began disassembling his pajamas/diaper.
Apparently he REALLY needed to go because he started to go before he sat. And proceeded to pee all over the crotch of MY pajamas (as I was squatted in front of him).
His pajamas stayed dry.
