Ca, that was not the reason I had kids, it's just I've heard a lot of people who looked back and realized that this is part of what having families is all about. You take care of them and they take care of you.
It's not about spending all your money so you have to move in with your kids, it's about the possibility that you might lose your mind, and who would you rather took care of you, some strangers, or someone who loves and cares about you.

I also agree with the gal who just said, don't have kids unless you are willing to give them your ALL, because that's what they need. Kids aren't like pets, you can't get rid of them once you don't like them any more. They are the most incredible commitment. When you're at your sickest, your weakest most miserable moment, your child is going to need you. Having kids taught me that I can do almost anything. And unless you are really lucky, you will find that your family support group tends to not be there when you need help caring for those kids. I think Raleighdon and I were child-free for 4 evenings in the first 7 years and 1 overnight.
