Know 3 kids (twins, and separate child) who were born through surrogates.
The twins in Ukraine from a German couple, and one in the US for an American couple.
For me, regardless of one's own opinion about surrogacy (including my own) in the case of the twins born in Ukraine, I don't think the family trafficked a baby. They made one. The twins are genetically theirs, they ARE the parents, they just rented a Uterus (to a consenting) woman to make them happen. Whether one should be allowed to rent a uterus, (or a woman's body) is up to opinions BUT saying the twins suffered from being separated from their mom etc...is completely wrong. They are doing very well indeed and never were, in fact separated from their parents so no ''bonding'' was altered.
Now the family from the US is different because they used both sperm and egg donations and also used a surrogate they met through a friend. So technically from a biological point of view none of them is actually the parent of the baby though obviously a contract was sign and the two people who made the decision to have said baby are legally the parents.
The surrogate was a friend of a friend who didn't want kids but wanted to experience pregnancy, she wasn't paid (which seem to be what most people have a grief with but personally I find women not being rightly compensated much more bothersome) and for having met her and been there the two times she's met the kid she gave birth to, she very very obviously (and vocally) doesn't feel any motherly instinct for him (or in general) and have absolutely zero interest in this kid nor feel the need to bond or interact with him in any shape or form, the kid also surprisingly had absolutely no interest in her whatsoever, in fact knowing the kid very well and how sociable he is, it's actually quite impressive how disinterested he was by her. I thought maybe something would wake in him but she was just another stranger for him and I think he could sense she had zero interest in him and therefore didn't care much for her either.
If you had granted this (lovely may I say) lady the custody of this baby she would have absolutely freaked out and would have just given it up for adoption. She doesn't want to be a mom, in fact, she never wanted to and forcing her to be a mom to a baby that isn't biologically hers and she didn't want would be as wrong as forcing someone to go through a pregnancy she doesn't want (which isn't really the case of surrogacy).
From a more ethical POV do I agree with genetically creating children and asking other women to carry them etc...? Not necessarily no, but I also talk from a privileged place of understanding that for some people, surrogacy is getting access to a life changing amount for kids those women do have and are trying to raise and get out of poverty. Me controlling their body and what they do with it, wouldn't help anyone. I also have more grip with parents who naturally conceive and are shit parents than people who work together to bring a baby to life who will be loved and well-cared for.
Also, I very much love the 3 kids I know from surrogacy, there is no way to wish for the end of surrogacy without wishing kids like them weren't born and I couldn't potentially wish that. Should women who want to help, be able to help? I think so, it's their body their choice. Should those programs be extremely regulated and checked? YES. Should women be paid for this? Yes, for me yes, I know that by adding monetary value you are opening the door to more people wanting to volunteer for money purposes but I would rather women who consider prostituting themselves for pennies to make a living, end up doing a round of surrogacy (if they feel it would work for them both physically and emotionally/mentally) and make a hefty living that would leave them and their kids set up for quite a while financially than them put their body and mind through gruesome things just to make ends meet.
I am from a country where surrogacy is illegal, yet people still do it, by going to to other countries etc... it would be much better to legalize and regulate it, than have situations like this were people have created a baby who is now apatride and blocked in Ukraine unable to come ''home'' and have a family and will likely end up in an orphanage for years.
It's not for me to decide whether or not kids should have been born or not and wish they didn't exist, there will always be surrogacy like there will always be prostitution/abortions etc... whether it's legal or illegal and in plain sight or underground so I would rather it's done legally and regulated than not. For the sake of everyone involved.
