That is the best word I can think of to describe Elizabeth when she is sitting in her playpen!
She is just plain BUSY! She's checking out her toys, grabbing at anything within reach, talking to her little caterpillar,...and generally just caught up in her own little world that is busy, busy, busy!
MUCH too busy to be interrupted by Mommy, who is trying to get a good picture!
(Don't you love the expression..."Do I have to smile again?!?!")
