For those commenting on this thread, I can assume the vast majority have encountered at least ONE adult with Down Syndrome.
This is not so in MANY Eastern European countries. Due to the lack of medical care, social awareness, and acceptance, the majority of children with DS are placed in institutions upon birth. At the age of five, many "age out" and are placed into adult mental institutions.
Does every child deserve a family? Absolutely! But unfortunately in this situation, the surrounding society and culture come into play.
If her story is to be believed (and I really don't see anything that doesn't line up with the father's version), then she saw an opportunity for her child she could not give him. If her story is to be believed, her husband gave her the option of raising him together in Armenia or taking his son to New Zealand and raising him by himself.
She made a choice -- one she felt best for her child. Many medical professionals in EE see children with DS as lost causes. Sure, she could have fought tooth and nail for his whole life. But for what? Sub-par medical and developmental care?
It's an unfortunate situation. But there really doesn't need to be an either-or battle in terms of sympathy and compassion. It wasn't too long ago that women in the US in the 50s were being told their children with DS were stillborn. It wasn't too long ago that doctors were using heavy duty scare tactics to scare women into giving their DS children over to the state. All because of fear of the unknown.
