Today Nina found a bottle of L'Occitane mouthwash in the garage. It says bain de bouche on it, which she has been running around saying all evening. She now officially knows more French than I do.

update:
later on in the evening, I was telling my mom about Nina's proficient use of French. I held up the phone and the "bain de bouche" and Nina joyfully shouted "mouthwash!"
