A Formula for Cuteness?

I don't give much thought to what growth percentile the babies are in. Probably because there are so many of them it's hard to keep track of it all. But recently I measured J. and figured out why he's so darn cute:

Height = 10-20th percentile (He's short.)
Head circumference = above the 95th percentile (He has a big head.)
Eyelash length = above the 95th percentile (Ok, I made that one up. But they are remarkably long.)

Three months ago J. was below the 5th percentile for his age in height, so he's making progress. But he still has a way to go before he grows into his head.
