Ok, since we all usually open up on here, I'll do it as well.
Our kids were conceived by turkey baster route, aka in-vitro fertilization.
I was the problem (no swimmers), so we had to get donor sperm. I often, during the pregnancy, wondered how I'd feel knowing that the kids weren't my DNA. The moment they arrived, I cared less, and 11 months later (on Monday), I still care less. I can't tell you how my times I teared up looking at them today...the 3 healthy, happy, smily, giggly, beautiful children...MY kids.
