Hey, let's not kid ourselves. Adults don't know that much. Let's see if a toddler knows what to do.
My son is 2 1/2 now, and I probably confide in him way too much. I trusted him to pick his baby brother's name: I held him by his ankles upside-down, and slowly descended him towards an array of 4 post-it notes possessing different names. It was a riveting case to present to my wife. And it was the name we chose.
Despite an irreverent fondness for "accidentally" plowing over his little brother as he stumbles around, my oldest son shows good instincts.
