Could not say for sure, but adoptions seemed to be on a regular basis. The two doctors had very caring reputations as I recall but it's all a long time ago now. At the time, I did get the impression that the girls were not pressurised into parting with their babies by the Fairfield staff but, again, I could not be sure.
I do believe that it was also a normal nursing/maternity home and ladies went there on a private fee paying basis to have their babies. A bit up-market you might say and, so I was once told, "a bit posh".
