My son Aran was diagnosed with PDD-NOS in June. Not really a surprise - you know how one day you just become aware that he's different somehow, and then that gut feeling grows? He seems like the other 3 year old kids at first, but then you factor in the screaming, raging fits when he has to stop an activity he  likes, and the 3-5 notes of little aggressive and tantrum-y acts at school each week, and the need for one-on-one intervention at school...well, you get the picture. Honestly, I was a little relieved when he was finally diagnosed, because I felt like I was losing my mind. I got vibes from friends and family that I was making something out of nothing, and that he would "grow out of it", and that he was no different than other kids, and why did I want to label him? I wanted to tear my hair out numerous times, and would get defiantly heated with friends and family that I wasn't imagining it, I had done the research, we had had doubts from 18 months, and I wasn't just trying to find an excuse for bad parenting. So, now we have a diagnosis, although the psychologist wants to reevaluate him in a year because he may be HFA or Asperger's, she's not sure. One hurdle crossed, now for the next, the dreaded IEP process. Need to get up to speed on all this pretty quickly. Meanwhile, some of Aran's behaviors are increasing in frequency. He spins when he's upset or agitated, and flaps his hands more now than he did a year ago. And other things, such as his eye contact and social behaviors have improved, I think due to putting him in preschool a year ago, and encouraging eye contact. But, anyway, I'm glad this group is here, because it's good to connect to other parents going through similar experiences.
