Once married, they were anxious to start a family. They were patient when it didn't happen right away. After several years with no pregnancy, they were discouraged, but still felt it would happen eventually. They visited their doctor, and then specialists, none of whom could find any physical reason that my mother could not get pregnant.
The circumstances that lead to adoption usually involve loss. I feel for the loss my parents felt when they were unable to conceive. I also feel for the loss my birthparents, who were teenagers, felt when I was relinquished for adoption. I know my birthmother loved me and was not given the choice to raise me. My brother's birthmother was not a teenager but his birthfather was a married man. Imagine all the circumstances, most of them involving loss, that needed to line up in order for my family to become my family.
I guess the full title of this post could be 'All because two people fell in love, found themselves infertile, two other woman had unexpected pregnancies and had to say goodbye to their babies at the same time the infertile couple finished their home studies and were approved to become adoptive parents and and finally the infertile couple found they weren't infertile after all.'
