Many of my friends were "surprise" babies. DH's mom was 42, best friends mom was 46, another friends mom was 44.
My mom had eight, the last at 40. My step sis is having her second this month and she's 40. My first was at 30, second at 33. First was the happy surprise and the second we got pregnant the first time we tried.
I think it all has to do with attitude. A great co worker had three kids with his first wife. He remarried and became a dad again at 48 (wife was 38 or 39 at the time). It was amazing to see how devoted he was to his little boy, and helped me through a really rough time in my life (my ex left me, but said he'd come back if I got my tubes tied). Bob would put pictures of his little guy where I could see them daily and tell me 'that's the best thing that ever happened to me. Don't give up your dream of kids to make someone else happy. Do what makes YOU happy".
Eighteen months later, I had my first! And he was absolutely right.
So, to paraphrase...if you want kids, don't give up that dream. You CAN have them later in life.
