Another perspective - my cousins mother died when he was nine months old, so he never knew her. She had cancer.
Dad remarried when he was about 8. During the intervening years, grandma moved into the house to look after the (three) children of which he was obviously the youngest.
There’s a widely acknowledged feeling that this is something of a tragic scenario. My aunt died, so she’s not party to the tragedy, though she knew she was dying. The real ongoing tragedy is the fact that my cousin never knew her. His older siblings have some memories, he has nothing.
Those of us who remember her have tried to give him a flavour of her personality. It was so long ago now, there are no videos or recordings of her. He’s always wanted to know in what ways he is like her. I think this intensified when he had his own children.
So for this reason, again through personal experience, I do question deliberately depriving a baby of its mother in the case of same sex surrogacy. Either being deprived of your mother is a tragedy or it’s not, it cannot surely depend on the circumstances when the child is a baby and has no recollection of those circumstances as they played out.
I’ve expressed this view to lots of people, their response is usually ‘as long as the child has two parents and is loved, it makes no difference.’ However that seems to be their opinion, and I’m presuming that most people opining as such have not actually have any personal experience on which they can draw.
For my cousin, he grew up much loved in a house with his father and grandmother. He was ‘patented’ by male and female relatives and later acquired a stepmother.
If it really doesn’t matter that he was deprived of his mother, why does it bother him so much?
