Andrew has a counting book that he likes to read over and over and over again. This becomes rather boring for the adults, so we've been counting in different languages: French, Spanish, German, Italian, Russian. (Note to self: need to learn to count in some Asian languages, beyond "Ichi, Ni, San...")
Today we did German. Apparently "fünf" is the funniest word in the world. Now Andrew is running around the house saying "fünf fünf fünf" and giggling.
The kid has, like, two words in English, and now he's speaking German.
