First tooth and almost crawling!!

Well our little baby is turning into a wild child!! Caleb's been scooting around now for awhile trying to figure out crawling..he is getting really good at it! We put him on the floor and in seconds he's over getting into something, usually not his toys but Daddy's playstation! Caleb's babbling like crazy now too, 'mama' 'dada' 'baba'...and many other undistinguishable words. A few nights ago I noticed something a little sharp on his lower gums...sure enough, it's a tooth popping through finally! We've been waiting for this for months now with all the drooling and chewing Caleb's been doing.
