Ping-Pong Balls?

Daniel brought home from Grandma's house some ping-pong balls two days ago. He has had them in his hands ever since. He eats with them, sleeps with them, and carries them around. Sometimes he only has one clenched in his fist, but most of the time they are both there. I think that this is what he will be attatched too! I am excite, this means that I can buy a whole bunch of ping-pong balls, and when one gets lost or broken, Whala! there it is!
