Irrelevant, I know, but I'm just musing why the word was used, when I've not heard it being used to describe children for years.
I agree it's a horrible word to describe a child, but I don't think the poster meant it that way. I don't think she meant to imply anything negative about the children who were being adopted.
That's why I wondered if it used to suggest that these children don't have anyone to look after them, even though there is often a mother forced into giving their child up for adoption. That is, a term used to ignore the mother because it's easy to deal with the idea that the child has no one, than deal with the idea that there is a mother with no choice but to give up their child.
Sorry for the derailment.
