Re: 'Shit, It's Twins!'
Oh yes. When my twin boys were born, we joined something called the Twins And Multiple Births Association (TAMBA) and quickly discovered that, almost invariably, whatever plans for offspring numbers the parents had started out with, the twins (or triplets, quads, etc) were always the youngest, even if they were the first. Make of that what you will.
And don't anyone try to tell you twins are twice as much work as one - they are at least 1,437 times as much work. And that's on a good day!
