hiddenmnetter you seem to be talking about surrogacy where payment is made.
I see the point.
But in my understanding this is not legal in the UK. So UK surrogates might have a different experience to, say, USA or India.
I can see comparisons but my only experience of knowing a surrogate was she did it to help someone and was not paid.
@PeachMelba78 you can speak about your experience however you choose, of course. However, I don't understand how you are not the biological mother ( or biological female parent). If you were not/ are not the child's biological mother, who was?
I do understand how you talk about it may/will frame this experience for you, of course. And maybe you are thinking of the child with her or his parents now.
Do you want to share your story or is it too personal? I admire you for coming onto the thread but don't want to pry. 
Just for the record we have a birth child and adopted. Prior to that had fertility treatment with donor eggs, we were encouraged always (in both processes - donor egg and adoption) to be honest with any children so that the child knew their own history. I think that is important for kids.
