Yes! As far back as I can remember, I always wanted to have kids. My first, a girl, was born when I was 28, and I had twin boys two-and-a-half year later.
If I could do things over again, I would have had kids sooner. My wife and I were married for over 5 years before she got pregnant with our first, and we think back to those years now and wonder what the hell we were doing. They feel like empty years. We had lots of fun, but there are so few memorable moments from that "era."
edit: I do want to emphasize that my wife and I had milestones throughout our relationship. We first lived together, then eventually bought a house, then got nice cars, then decided to have kids. We thought it was important to be stable both financially and in terms of our relationship before starting a family. We were lucky to be able to do it on our terms!
