There is nothing you can say that I will feel anything but extremely proud that I was able to do this for 3 families
And at no point did I or anyone else suggest otherwise. You do you. (I hope the kids - all of them - are ok.)
Some babies are like that. It is possible for a baby born through surrogacy to be laid-back and responsive.
Yes, each baby is different - some do things others don't. Some like things other don't. It's as possible for a newborn taken from their mother to be fractious and upset as it is for a newborn to be settled with someone they don't know. There is no predicting it.
What we do know from decades of study is that babies who are with their mothers do better than without - unless there are clear and present dangers. That's why, I'm developed countries, we have social services and even that doesn't prevent injury, trauma and death (though there are failures I do think/hope for the most part that SS are doing their best under enormous strain).
Adoption prioritised the child and as this thread demonstrates well, surrogacy prioritises the adults.
but you have no evidence that it is in this set of circumstances.
I have the response "because I could" and because it made other people happy. That's 'evidence'. That's why I asked.
Women die during pregnancy/childbirth.
Exactly, and that can't be predicted that much either. Risk can be assessed but women who have had easy pregnancies and birth may go on to have hyperemesis gravidarum and emergency hysterectomies.
This could happen to a woman whether she gives the baby away or not, it can happen whether she is your cousin, or a woman you have a contract with, as a surrogate mother or not.
Is there a way to guarantee a woman who is a surrogate mother with have not adverse effects, before, during or after? No, there isn't. There is no guarantee for any woman as pregnancy and birth are unpredictable biological processes and it is only that a risk that can be reduced not eradicated.
