I blew that one. First one left for college followed by the second getting ready to leave and I thought "wow, young mothers get left behind." Soooo my oldest is 36 and my youngest will be 16 in May.
I have your's and mine and did once have the your's mine and ours. Between Bill and I our combo was 10, 6 of mine 4 of his, but I never leave out the 4 boys from before, so sometimes I say 14, usually 10.
We have 28 gkids between us, most are mine, but since grandpa is gone now, I get them all. Just never hear from the 2 oldest stepkids who I've never even met after all these years. Still, they count.
