I know a wonderful couple, their kid was born with some Downs' syndrome and a congenital heart defect, Dr. told them to just put him in an institution, they looked at each other then at the Dr. and I won't repeat what they said as I'd have to give myself an infraction.
I got to know them about a year later, kid was just getting big enough for surgery to be possible to fix the heart issue, they were doing PT with him in preparation for post surgery, then they had the surgery done to fix his heart. So they were having him stand up and sit down, feet in boots that were screwed to a board, to strengthen him post surgery.
Was going there to practice skills but got to watch as their kid got stronger and better off...
Couple years later, a local woman who was addicted on crack cocaine and who had a similar age kid, got jailed; They knew the grandparents, so when they heard that the grandparents were having to chain the kid to a tree to keep him from running out into traffic etc., they offered to adopt him, and did so.
Two kids, pretty similar except one has heart surgery scars and the other has anger issues from a bad childhood, they worked with this kid and made amazing progress, he was running around with their kid (double trouble!) and the two kids were learning from each other.
Lost track of them after a while due to my work, but I saw a good couple, had at work to improve both kids' lives, great people!
A little help can make a big difference, definitely; Parents with ethics and good parenting are wonderful
