I always wanted children, I grew up in a wonderful family with a SAHM homeschool Mom who had me at age 20..and I wanted to be just like her when I grew up. I didn't end up getting married until 23, and though we both wanted kids one day...financially it was out of the question for a few years. Then I got really sick at 27 (feared for my life), right when we had decided to TTC in a few months. I had also always wanted to adopt, especially from Russia as I have been to Russia several times and have worked with orphans there,
Thank God I have finally been well for several months (age 29 now), and right when my health returned I decided to take life by the horns and either TTC or start the process to foster-adopt (would love to adopt from Russia but don't have the $$). We just initially went to the information session July 1, 2010, and it slowly built on us. Once we decided to do it, it has become more and more sure that this is what we should and WANT to do. Just 2 years ago I was on these forums in tears about wanting to TTC but being ill and in debt. Now my desire for bio children is gone, I truly want to foster-adopt with all my heart. DH is pretty convinced almost everyone can do it- our society depends on it. And my heart continues to stretch: where I started out wanting 1 baby, now we are taking 2 children, and we are currently signed up for ages 0-4 but we will probably up that.
So don't do it because I tell you to, but I agree with PP that if you are drawn to it and DH is supportive (that is huge, I have friends who really want to adopt but their DH are against it)...why not? Not that it is easy or the decision should be made flippantly, but it really could be worth it.
A guy who spoke at our training (I forget the title, he is with the CPS unit that actually physically removes children from homes) said it best: "All these children want is a family. All you have to do is open up your home and love them. It won't cost you a lot".
Warmest wishes to you.
