I have to say, one of the best things about having kids is to see and hear them work out language. I may inflict on — whoops — regale you some time later with some of my own daughters' inventions, but for now I'd just like to send you over to Beta Dad, who's discovered how wise his adorable twins are.
One of them coined the awesome term Daddyjuice to designate Beta Dad's favorite libations: beer and coffee. Check it out here. And while you're there, enjoy the rest of his writing, too. I do so often, with my own favorite Daddyjuice from Scotland.
