I too am one of ten, only I am the second.
Oldest is 22, youngest is 3. My folks didn't/don't seem to have any problem with taking care of us.
Sure sometimes it takes time from other things and costs money but they do not regret having us all.
And I'll tell you, we had a ball!
Yeah, the hardest time I had with raising children was my first. It seems a though once you have three, having any more than that is no big deal.
My parents took us camping in Northern Michigan. Of all the memories we have those are the ones we talk about the most. "Remember when dad stubbed his big toe on that tent stake and instead of cussing he just said, 'Gee, that felt so good I think I ought to do it again.'"
