thanks for the book recommendation!
ds1 hasn't asked questions as much as he's made statements. he jumped on top of me the other day and yelled "sex!" while laughing hysterically.
i tried to explain to him that is something mommies and daddies do when they are in love and it isn't something that little kids do but i don't think that was enough to satisfy his curiosity (or week long obsession with the word).
