For a long time (read: years) I have struggled off an on with epic bedtime battles.  Generally my oldest, Baby Duck, is the primary issue with only slight occasional backup from Ladybug.
Tonight, after a two hour battle, I finally went in their room and laid down the law.  "Go. To. Bed.  Do not come out of your room again FOR ANY REASON!!!"
Baby Duck immediately delivered her usual rebuttal: "But what if we have to go to the bathroom?"
Tonight my immense frustration took over and she got a different answer.  "Just pee the bed, then!  Goodnight!"
Not ten minutes later, Ladybug (a.k.a. Miss Literal) did it.
Mmmm, crow.  Tasty.
