"I want my last accomplishment in life to be the topic of a FR thread."
LOL!
Seriously though, though it would be wonderful to hold another newborn in my arms, I'm (recently!) 42 and cannot imagine having the energy to have another baby, even if the baby were healthy. I hardly slept the first year or so of the lives of both my children. :)
I just turned 40 yesterday and my wife is 42. Our oldest is pregnant now. After 8 kids, it's about time we get to hold the babies and have no responsiblity =)
