Here's one of my favorites shots of big brother Colin during his first week. I take it back: maybe they do look pretty similar. I'm comparing Cameron (who is asleep on my arm this moment) and this picture, and there are lots similarities: particularly, the shape of the head, the ears, and the mouth. Of course, Cameron's looks are changing daily, if not hourly, so we'll see how things evolve.

As Fedora's mom pointed out, Colin did seem to be chubbier despite Cameron's outweighing him a touch (less than 4 ounces).
