new word, please!

Drew's has been picking up new words faster lately. He can say dog, dad, that, mom, bye, hi and now BALL. This word...BALL! For some reason and the object it refers to, have become obsessions of my little toddler. At 16 months old, he is crazy about BALLS. That's all he wants to play with and all he wants to say!!!! After hearing the word BALL repeated 37 times in an hour, a person can go slightly cRaZy! Drew, it's time for a new word....PLEASE!
