I got this question today from my child-free by choice friend. She and her husband don't want kids, and that's totally cool, and they don't understand 'why' we are having one!

I told her that our family didn't feel complete yet, and that I knew DH would be an incredible father, and wanted to see that happen!

When people ask you this (kinda nosy, I think) question, what do you tell them? What *are* your reasons for having/wanting kids?
