Anyone out there a fraternal, identical or Irish twin/triplet/multiple... or have a set of your own?

I'm an identical twin and sometimes I get sad that Charlie doesn't have a twin of his own... plus then we would've been all done with having kids all in one shot. But then I think about how hard Charlie was, and I can't imagine having two little Charlies waking each other up at night!

Anyway, anyone out there a twin or multiple - or have some of your own?
