Know what he did?
First he closed and locked all the doors and windows.
Then he got her a snack.
Then he read to her every Virginia Lee Burton book that we own. He said this took him a whole hour.
Then he was thirsty and hydrated himself and gave her a drink.
Then he helped her set up his best trucks on the car mat.
Then he read his own book while she played underfoot.
I showed up just as they were cleaning up.
Pretty much the best babysitter ever.
Although I'm not sure he is interested in doing it again anytime soon!
