I know that many infertile couples, or established families, turn to adoption as a way of creating happy family units but I wonder how many realise that having an adopted child - especially if it's not newborn(ish) - realise what they're getting in to. Children that are available for adoption almost always come from horribly dysfunctional families and that the children, unfortunately, have inherent issues, some of which will never be overcome by love/best intention.
It's my view that if childless couples/singles think that they will be able to form ready-made happy families with the type of children who are up for adoption then they are going to have a rude awakening.
