I already have 1 child, a 2 year old daughter. My fiance had her shortly before we met. Her biological father in not a part of her life and never has been. I'm the only dad that she has ever known. I am going to adopt her after my fiance and I get married. I love her more than anything. She isn't my blood and I wasn't there through the pregnancy or for the birth, but I feel such a strong connection with her that it doesn't matter. I'm her daddy.
My fiance and I have also decided that we want to have another baby. We went through a sperm bank. It's awesome how you can choose your donor. I put in all of my characteristics, interests, and ancestory and it found donors who matched. I was able to view family history, activites the donor was interested it, height, weight, shoe size, hate size...everything. I was able to hear his voice. It had all of his medical history (all the way through his grandparents). After finding someone who fit my personality pretty much 100% we ordered his lifetime photos and were able to see the donors baby pics all the way through his present picture. Weirdly enough, when we got his pictures, he looks so much like me you would think we were related! I'm so excited to start the process, go through the pregnancy with my fiance, hear the first heart beat, find out the sex, cut the cord, and hold my baby in my arms the day that it's born. It will be the most amazing experience of my life, and I don't care one bit that the baby won't be biologically mine. It will be my son/daughter and I will feel as much of a connection with that baby as any biological father would.
