Elena and Sam were playing some version of tug-of-war upstairs while I was feeding Charlie when I heard the start of a cry. It sounded like a cry of pain that would soon escalate, but it went silent almost as soon as it began.

A little while later, I heard Elena say, "Sam, you're the best brother ever!"
Sam: "Why?"
Elena: "Because you knocked out my tooth!"

She was so happy to have it out, she doesn't even care that we can't find it.
