We have several adoptees here - how different were N&J as far as your own experiences go? What preparation did parents receive before having a baby handed to them? Someone having a biological child, have time to prepare both practically and emotionally - it sounds to me like they were left to get on with it. I imagine they did their best and certainly didn't deserve to die in such horrendous circumstances just because they adopted two kids.
From what I've read about NB he sounds similar to my own adoptive father. Although you would not find my dad having anything to do with religion. In terms of my adoptive mother again she has no interest in religion, although wasn't as anti as my dad, but she is far more Liberal minded than June.
Babies put up for adoption during the so-called 'baby-scoop era' were in the main as a result of societal stigma attached to illegitimacy which was to some extent all bound up with the Church and religion.
To my mind I think June finding herself infertile and adopting children created real paradoxes for her: Why had God denied her birth children and how could she bond with these babies who represented everything she despised ie babies conceived outside of marriage? And this is before you have all the dynamics I described above.
It was only ever going to end in tears
