Unfortunately, there still seems to be a stigma behind disability, so families won’t always know how to behave or deal with their child or sibling’s disability.
I think another reason why families, don’t always know how to deal with a disability is because they’re simply not equipped to know how to help or deal with their child with the disability. Siblings aren’t sure either.
Families are often embarrassed by what they deal with, so instead of learning to embrace their child’s disability, they shy away from it instead. Sadly, society still doesn’t make things easy because it’s still less accepting of disability. We’re not moving forward quick enough.
In my own case, I believe my father not wanting to know, was a culmination of embarrassment and not being able to cope with the fact that his child was born with a disability. It tends to come through our insecurities and although parents are often well intentioned and my parents were underneath, our ability to cope decreases, once reality sets in and the task in hand becomes too great.
However, and it is still my view that the more society is accepting of people who deal with disabilities, the more families will learn to be accepting, the less they will need to deal with the stigma.
