Cal Crawls!!!

About 3 weeks ago Cal started trying to crawl.... legs and arms flailing. The past few days he has been getting up on all fours and rocking. Tonight he finally crawled!!! He only went about a foot, but he did it! Would you all like to know the secret??? A pen! I had it in my hand and then put it in front of him and he started reaching for it. It was so neat to see him finally crawl and figure out that he can move forward.... watch out Gamma! He has also started making farting noises with his mouth. We have not been successful getting that on video yet.
