Just exactly HOW MANY are there?

Nine. There were exactly 9 sippy cups in our playroom. So when Ronan asks for his cup of water and I rummage through the cabinets like a racoon in a garbage can and cannot find a darn cup, well, I know where I'll look. The playroom. The room that I gave up, so that the kids would have a place to play, lounge and, well, store sippy cups.
