Just found out that the wife is pregnant with our 3rd now (we were trying). Our first, our daughter, changed my life completely. Since day one that little girl has had me wrapped around her finger. She will be 7 in a few weeks. My boy is 2.5 years old. He is an absolute asshole. Still, love that kid dearly.
Kids aren't for everyone. In today's society I see more and more people either staying single, or getting married and not having kids. That's cool. To me, if you don't want to have kids, great. Don't pollute this world with something you aren't going to be able to handle, control, or maintain.
To those who say how hard it is, and how expensive it is to have kids, that's not always the case. I think kids are super easy to raise and maintain. Wife works part time now, and when she does work, I don't work. Saves us a ton on sitters and always leaves someone home with the kids. I realize that is not achievable by all, but if you are willing to bend your life a little around your kids and not be so selfish, you can work things out. As for the price, again, I don't feel it's outrageous. If you plan ahead, budget correctly, and figure out your NEEDS, it's seriously not that bad.
Of course the wife and I had fun the 11 years we were together before kids, and of course we would still like to take those occasional trips (day trips usually) alone, but our life is much fuller because of our kids, and because we get to experience it with our family.
