Time is the key, honestly. It's all based on how these children are. Every child is different. Every person is different. It shouldn't be time-specific. If it takes longer, they deserve longer. If treatment isn't working, there should be a broad spectrum of available research just to be able to develop treatments for other people. Some treatments work for some but not all. It can't just be a blanket. There needs to be research and there needs to be a lot of time put into deciding which path to move forward on.
I don't think there's one solid, good answer. I believe if time, structure, education and all of these things were followed, there would be a good program in place and this stuff wouldn't happen to our children and our people.
