I don't like this constant referring to mothers of donor children "deliberately" denying their children the right to genetic knowledge, as if the known donors were queuing up but we turned them away.
I always wanted children, and when my fiancé dropped the bombshell that he didn't (having previously said he did) when I was 36, I was devastated. I knew my chances of meeting someone else "in time" were slim, due to hormone levels I'd had tested etc. I grieved the loss of the family I always thought I'd have, and I thought long and hard about my options. I read everything I could find on the subject of adoption and donor conception.
I feel I went into it with my eyes as open as it's possible for them to be. I would have been very happy to have a known donor, or a donor who waived his right to anonymity, but in those days they were all anonymous. I had no choice in the matter.
I worry constantly about how my DC will feel in the future, and I try to be as open and receptive to discussion as possible with DC1 (age 8). I admit to him that I know it's hard and that I'm sorry that he doesn't have a father - although so far the only time he says he wants one is when he sees his best friend getting more Lego than him, which he attributes to friend's father's well-paid job!
I think there are many ways that, as parents, we do things that may blight our children's lives. But we weigh up the pros and cons, and try to make sensible decisions. For example, a friend of mine has a son with fairly significant physical disabilities and learning difficulties. He will never be able to live independently, but despite knowing this they still had a second child. DC2 is now growing up and feels embarrassed of his brother at times, and faces having to look after him when their parents die. Is this wrong? Should they have done this, knowing that they were setting DC2 up for a life that may make him unhappy? Who knows? Should disabled adults have children, knowing that their DC will have to be their carers? Should people with genetic conditions have kids, knowing they'll pass their conditions on? We can't predict the future and how people will feel, but we do what we think is right.
In my dark moments (like after after reading the Anonymous Us link) I feel sad and worried about what I have done. But I really do try my hardest to do the right thing for my DC, and I am optimistic that they will be OK.
