I'll get right to the basics of us, we live with PDD-NOS; Pervasive Development Disorder, Not Otherwise Specified.
It's a label doctors give children when they know something isn't quite right, but they can't really figure it out, and, frankly they are tired of dealing with the parents. It identifies the child as being on the autism spectrum.
Here's the other great thing, if your child has been labeled with an acronym, they usually have at least one more. We also have ADHD, RAD, and ODD. That means my kid has a lot of issues. That also means life is never boring and it gives me a ton to write about.
