Most of the special-needs care I have provided has been to my own brother, who has Autism. I cared for him since I was 15 and up to age 19, while my mother had to go to work, and I absolutely loved the experience!
I have also worked with children with Down Syndrome and other disorders. Additionally, I spent 1 and 1/2 years at a psychology lab at the University of Connecticut as a research assistant, and it was there where I had even more exposure to other developmental disorders, although the lab I worked at was focusing primarily on Autism.
I am convinced that the best way to provide care to children with special needs is to do so with love, respect, tolerance, and compassion.
