Our family has adopted many times......internationally, through the foster care system (all three failed in some way), and through domestic agency/attorney transracial adoption. In total, we've had six infant adoptions. We knew when we dated over 35yrs ago that we'd adopt. We didn't have fertility issues and adoption was our first choice in making a family.
We DID encounter biased caseworkers and those who felt we were 'odd'. One reason we chose to adopt was due to diabetes and severe arthritis that runs in our biological families...though neither one of us has these...nor did we have them back when we were in our 20's and first adopted. However, more than once, we had to 'prove' we truly wanted to adopt by discussing these issues with an MD, or by showing our sincerity by going through questions when we had homestudies conducted. It always irritated me....but it was yet another hoop to go through in order to adopt.
I agree with the poster who mentioned some bioparents might not choose a couple (single) who didn't have fertility issues. I've seen that. But, along with that are bioparents who DO want couples who've chosen adoption over giving birth...so it can go both ways.
One time out of frustration, I DID say to my dh, "You know, giving birth would have been SO MUCH EASIER!!!!"....and it would have been. There're so many double standards when it comes to birth and adoption---it's ridiculous. But, it is what it is and we've always felt adoption was more special---if not more so---than giving birth. That's a motto that's long been said in our home...and two of the infants are now grown and on their own.
Good luck in your adoption journey.
Sincerely,
Linny
