Like all things that are clearly superior to the competition, Isaac needs a certified nickname. I've been calling him Isaac, The Hurricane, Squirtle, or Little Man. Shannon tried to call him "Izzy" a few times, but a few swinging arms (mine) and two missing teeth(also mine, don't ask) later, that stopped. As a child, I was "bear," my brother Tim was "tiger." My friend Dan's "bear" nickname stuck into adulthood (as did wearing diapers), and was turned into "husbear" by his wife, Katie (it's a portmanteau! A PORTMANTEAU!!!).
So, I'm taking an informal poll. As always, the best way to rear a child is to let internet strangers do it for you!
