Now? What about now? Now?

Nicholas has already started with please, please, please Mommy when he wants something. I thought that wouldn't come until much later and now it's expanding.

We were driving home and he asked for some juice. I told him I didn't have any juice in the car, we could get some when we get home. So he proceeds to ask me the last 10 minutes of our drive:

Juice now? You have juice now? What about now? Now you have juice? Do you have juice now? Now Mommy? Juice Mommy? You have juice now Mommy? Mommy juice now?
