and for those of you who don't know me...I am the mother of a 6 year old son who was diagnosed with PDD-NOS. Actually, we have been given all three diagnosis on the spectrum depending on who you talk to. The Neurologist said Autistic Disorder, the Child Psychiatrist said Aspergers and the School System had someone come and diagnosed Michael with PDD-NOS. All I know is he is the same little sweet, funny, wonderful kid that is a blessing to my life.
