When I first read your question I was a little confused. I had to stay home for my children sake. As the primary caregiver, I feel more at ease that they are with me instead than with someone that may or may not care for them in school.It's rewarding and they teach you more than you might think.
If this is not your child, and you are refering to be a child care facilitator, its a little more complicated. In any case, information and preparation is key. I have been working with special needs children for over ten years, it can be emotionally taxing. ( It hurts to see them struggle) But love is an ingredient that must be in the mixture. To tell you the truth, its hard to not get involved emotionally. At least for me. Good luck !
