What did he just say?

I am such a little chatterbox, the older I get the more I talk and talk.  The funny thing is that nobody seems to understand what I am saying. My grandpa calls it alien talk but I know exactly what I am trying to say, its the big people's faults for not figuring it out. There are some words that I say that the big people can understand and what is even more exciting is that today I said my first sentence!

Sentence:  Where's the ball?

Words I say:  ball (1st word), Mama, Dada, on, off, light, cow, car, Uba, Grandpa (gampa), ouch, hat, water, basketball (bayketball), two (do), baseball (bayball)
