Why is everything a disability these days?

The trouble is there are people with 'Real' disabilities if my son didn't have his 'Label' he wouldn't have the help he has been getting, and the remark being not good at sports is totally irrelevant isn't it because of course that isn't a disability, i agree there are some professionals and parents who do want to label their child just because they may be a little 'slow' or not doing what they should by a certain age, but not everyone is is this way, we just want whats best for our children or family
