What can I say, he's a Super-Genius! Yep, our boy found out how fun it is to suck your thumb. It always is fun to see how he becomes more and more aware of his surroundings. He is also starting to respond to your voice and sounds. When in his swing, he loves to look up at his mobile and watch the little stuffed fishes spin circles. Anyway, you can't help but love this little buddy and be amazed by how learns new things about the world around him, everyday!
