I've learned that many developmental disorders  are there from the time the child is very very young
I have heard that too, do you have a child? If so, do they have any disorders?
Yes, two.  We thought one had some autism type issues but she has since outgrown them for the most part.
That is very good. I hope that when we have kids they don't have any issues. We have friends who's kids have disorders, it's so sad.
They can be language issues, learning issues, motor skill problems or things on the autism spectrum.  It's hard.
Do you think that it takes extra love from parents when kids have these types of issues?
I definitely think so - some issues improve but a lot of them continue through adult life.
Do you think that society should treat kids/people with said disorders with special privileges? 
I think they definitely need more access to better care, some of these involve some pretty hefty impairment.
I have a friend born blind and Target just let him go because he couldn't 'do his job' even though he worked there for 20 years! So sad, it was because of a new manager.
