You're right. I had no idea what I was doing and sometimes I still don't! What I do know is that there are tons of things I said I would never do. That didn't happen. And, I would trust someone well-versed in the subject regardless if they had kids or not. When I took them to the doctor as babies and kids, I never asked the doc if they had kids of their own. That didn't matter to me and I didn't even think about that until right now.
