Words?

Mom has been hesitant to let me tell everyone that I have words. I guess she just wasn't sure if she was being a hopeful mommy or what but other people have recognized what I'm saying. My vocabulary includes Oz (which was my first word and for those who don't know, Oz is one of my dogs), dog, dogs, this (which sounds more like "dis" and is accompanied by a pointing finger), that (sounds like "dat" and accompanied by a pointing finger), and dada. I'm also working on bye-bye, right now it sounds more like buh-buh. Sometimes when I've done sometime I know I shouldn't have done I've been heard saying a mischievous "oh."
