Yes I would of terminated my own child.
As a gestational surrogate we discussed this prior to surrogacy and I did say that I would be ok with terminating if thats what the IPs wanted. As I would of been ok with carrying a child with a disability to term regardless of level of viability. Of course I do aknowledge that some surrogates have faced these situations and found it very difficult to continue with what they have said they would agree to do, this baby has shown no sign of any disability as yet (22w).
We also discussed if the intended parents (the babies biological parents) would still commit to the parenting order if the child had any form of a disability and they did say they would.
As a point of interest regarding surrogacy here in Australia, the birth mother and her partner (if any) are legally the parents of the child and go onto the birth certificate, parantage is granted to the intended parents via a parenting order that cannot be completed before 30 days, and not after 60 days than the birth certificate is destroyed and replaced. If anything were to happen to any of the parties involved before the parenting order is in place you cannot have one done and the child/ren forever remain children of the birth mother (and father if any) ie even though you could place them up for adoption you would still remain on the birth certificate.
