9 months old and crawling!

Zach is nine months old, and I just cannot believe it!! He is 27 lbs and 29 inches long...big boy! He's crawling everywhere, pulling up on everything, clapping his hands, and waving to everyone. I won't be surprised if he is walking before his birthday! He is so curious about everything, but I have noticed the slight onset of "stranger anxiety." I knew it was bound to happen. Other than that, he's wonderful.
