You misunderstood. Most of these mentally ill should not be raising children. This is a huge part of our current problem. Not being able to breed is actually damage control.
These are not the mentally ill.
That said, I have two friends, both mentally retarded, hard workers, very quiet and gentle people, that married and had a child. They have a daughter. They loved and adored her but since they worked long hours in lower wage jobs (initially, when they were young) they couldn’t spoil her even if they had wanted to.
They proved to be excellent parents. They were always home when she was to watch her do homework, they didnt go out and leavers her with a sitter or put her in day care, they didn’t get drunk or throw away money on drugs or entertainment.
She turned out great- she is of better than average intelligence and graduated very close to the top of her class. What is more, she adores her parents. She said that she learned she was the luckiest kid in the world- all of the kids who made fun of her folks were always complaining about and even fighting their own folks, or got separated in divorce fights. But not her. She said she always felt loved and wanted.
