Incidentally, also on adoption, but using the experiences of adopted children to support an anti-surrogacy position is also nonsense. Claiming that the very fact of being removed from a birth mother at a very early stage will cause significant attachment disorders is just evidence free nonsense.
Yes, babies who are denied nurture in their early days have lasting impacts from that. But that nurture need not necessarily come from a biological parent. That is why a child who is removed at birth is less likely to develop attachment disorders than a child removed at 2 or 3 years old.
Also, the whole discourse ignores the many other factors that are often present in adoption cases - the fact that a child might often be exposed to drugs, alcohol, violence or significantly raised cortisol in utero, often contributing to lasting developmental, learning or behavioural challenges.
And that's before you get into the variability of experiences depending on how adoptive parents approach adoption, birth family contact and life story work.
So please stop using the difficulties many adopted people face to justify an opposition to surrogacy.
