No such thing as an ugly baby? That's politically correct but ... It's apparently easier to analyze why babies make us smile.

Wall Street Journal columnist Robert Lee Hotz sums up findings from researchers at Oxford, MIT, USC, Vanderbilt and elsewhere: There's a sliver of your brain (fusiform gyrus in your temporal lobe) that's activated in milliseconds when you see a baby, making you smile. And it's a response that's too fast to be under your control.

Presumably that means, innately, we are all parents at heart.  Meaning those who believe in ugly babies should also be smiling on seeing them.

(In the interest of self-protection, as someone who owns a home that's a favorite nesting area, the only truly ugly babies I know are newborn mourning doves.)
