Big A Little a . . . What begins with A?

Here's Owen with his leapfrog letters--he surprises me with how many letters he recognizes and how he both sings the Leapfrog "V V vuuuh vuuuh" and the Dr. Seuss "Baby barber bubbles bumblebee" which sounds like "bubabrb bumbabee". His favorites so far are A, O, E and B. But this morning he surprised me by picking up little v and little f and singing both letters. We may have a voracious little reader on our hands! I'm thinking a little e.e. cummings and James Joyce next? Although he may just get Whitman and Woolf first--which certainly wouldn't be a bad thing. Especially since W is another of his favorite letters. . .
