After about two months or more of agonizing ("what if he looks ridiculous? What if I cut his ear off?") I finally cut Jonathan's hair. We put on a Baby Einstein video (thank you, Jessica!) and Gabe helped keep him still and gave lots of moral support and a few suggestions.
I didn't cut his ear off, and he definitely doesn't look ridiculous. In fact, I think I can safely say that this endeavor was quite a success. :) Check out the before and after pictures:
