Update: So we saw the pediatrician and she said she "definitely" thought DS was on the spectrum, but she was also very optimistic for his future.
We got a referral to a developmental ped and are waiting to hear back. The regular ped didn't think we would have to wait more than a month to get in, so that's good.
We also were referred to speech and OT. First speech appt is in-home next week. Can't wait to get started! Thanks again for all the good advice.
Also: We managed to get through library story time with minimal fits and wandering off! It's the little victories.

Hi all, I'm a mom of two (DS is 3, DD is 8 weeks) and recently came across this board (also a longtime April 2014 lurker). DS was recently screened by our public school system and was found to have delays in speech, fine and gross motor and adaptive behavior. He qualified for the special Ed program and got an IEP but won't start until the fall. He has not been diagnosed with any specific disorder but I have been reading up on PDD-NOS and wonder if that's it. My question is, what can I do next? School is 2.5 months away, and it's shaping up to be a long summer. Do I need to take him to the ped and get a referral to a specialist? There is a Brain Balance in my city; can I just call them up, and do they even take insurance? With a newborn on my hands all day, I'm already at my wit's end and it's barely June. I just want to have a conversation with my son without him responding about something random he read in a book or saw on TV (echolalia) or go somewhere new without a fall-on-the-ground tantrum. Or watching him walk on tiptoe or cock his
head. Or changing stinky diapers (he's vehemently against potty-training). i could go on. Or am I worried for nothing- is a delay just a delay sometimes? Sorry this was so long. I just don't know what to do or if we need to do anything. Any advice or thoughts are appreciated. TIA
Re: Update: Intro and developmental delays
If you can get a referral from your pediatrician for a developmental pediatrician or psychologist to get started on a evaluation. It can be months to be evaluated but you could request to be called if there is a cancellation.
In the mean time you could easily get referrals for speech, ot and pt from the pediatrician. The developmental pediatrician or psychologist can give a referral for ABA services. (I am not sure a pediatrician can give a referral for ABA, you can ask).
My son has PDD-NOS under the DSM4. It is all autism under the DSM5.
@-auntie- Both schools are ok with diapers. I know it could be a while (Pampers only goes up to size 7 though and we're pushing that- eek!) As for the speech plan, I'm not sure of the specifics.
Thank you all for your feedback. This has been a lot to take in and I'm still learning a lot of the acronyms.
We're just starting this journey, and I'm scared to death. It's really overwhelming, especially since autism is so complex and seems to affect each kid in a different way.
I have to keep reminding myself he's still the same little boy he was yesterday and no label will change that. Trying to look for silver linings but it's mostly "at least he can do xyz" or "at least he's not xyz," etc., which only help somewhat.
Plus, I feel guilty about how much thought and time and energy I put into him compared to DD. She's already 8 weeks and I feel like I'm missing her babyhood (although this may be a typical STM thing, who knows).
I'm glad to have found a supportive, knowledgable community. I don't have anyone IRL to talk to about this. I hope to get to know you all and reciprocate the encouragement and support where I can.
P.S. Visit with the regular ped is Monday. Will update.
