We are watching our favorite show "So you think you can dance." The girls love it as well. At the beginning of a dance, the boy and girl kissed.
Riley: Oh my gosh! They just went mouth to mouth!
Jeremy and I looked at each other. Then I asked "How do you know about mouth to mouth? And where did you hear that phrase from?"
Riley: Umm... I don't know! What is mouth to mouth?
Julia then turns to Jeremy and holds his face while saying "Daddy, I'll show you mouth to mouth." Then she kissed him.
We explained that the phrase can mean that they're kissing or that someone is needing help breathing so the other person breathes into their mouth to help them breathe.
Jeremy: This is only the beginning of life... of lots of new questions.
