I don't think it's crazy at all. I wanted a baby when I was 18 and I made it happen. We weren't married at the time and we have no regrets at all. That was 5 years ago. My cousins were adopted and since I was 3 I've wanted to adopt. Fortunately I found a man who wanted the same thing. So now we are trying to adopt for the first time. At 24, dh is 29, we are still considered young by some I think. We love being parents and want to give our ds a sister. Many countries require the parent to be 18 and you don't even need to be married or attached to anyone. The hard part is getting certified by an agency at a young age in the US.
But I wish you the best of luck. Continue doing some soul searching and some research.
