Babblin' fool

I don't *really* think that Luke is speaking in sentences yet, but man sometimes it sure sounds like he is.
Examples:
Every time he picks up a toy or book, he "says" proudly, "I get it. I get it."
When he's mad about being put to bed or in the car seat, he "says," "Ah Duh!" over and over, which sounds a lot like "All Done!"

It's likely just me hearing what I want to, but a mom can believe her 8-1/2-month-old is a genius, right?
