Youngest daughter is the only one-year-old I know who has mastered the Sneeze Ritual.
When she sneezes, I tell her, "Bless you!" in a tone of voice that one might also use to exclaim, "Wow, your head just exploded!"
She says, "Think-oo!"
"You're welcome," I say.
When I sneeze, she points her finger accusingly at me and says, "Bahs-oo!" with the same undercurrent of threat she uses when she sees the cat on the kitchen table and shouts, "Dit DOWN!"
"Thank you!" I say.
She is a very thoughtful one-year-old.
