One of the nice things about having two boys is that I will get to compare them. Not in the, "Your brother never pulled crazy stunts like this!" kind of way (because those comparisons happen regardless of gender), but more in this kind of way:
Hank is on the left and Johnny is on the right. They are about the same age in these pictures, though Johnny was 10 days early and Hank was 3 days late. Look at how much bigger Hank is than Johnny! He's got chubby cheeks and a double chin going on, not to mention how pink he is... which could also be lighting, but Johnny was jaundice, so he was more yellow than Hank. However, I think they look like they're related, don't you?
