2 year 0 month son - Possible PDD

My 2 year old son has a speech delay.  I got a referral to NC's CES (early intervention) when he was 19 months old & a program manager & therapist came in to do an initial evaluation.  He was not deemed as having anything but a mild speech delay so we started him weekly with an educator that came into our home weekly.  Since having her start his vocabulary has increased to 20-35 words, some "sounds" for words, & knows the sounds of several of his alphabet sounds.  However at his 2 year wellness visit our ped. suggested that he be referred to a dev. ped. because of his speech delay -but early intervention does not underst& why & has even recommended we get another ped. Physically he is right where he should be & socially we don't see any problems - he loves other people, other kids etc.
I have been given the M-Chat at 18 mos & 24 mos & he was low risk on both.  I have taken the PEDs, ASQ, & ASQ-SE - he was low to moderate risk on the PEDs because of his sp. delay & low risk on the ASQ/ASQSE; or rather "your child seems to be progressing normally at this time.  "
I guess I am looking for some insight on if we should go through with the developmental ped. or as CES is recommending move forward with his speech therapy only because he doesn't show any other signs of problems. see post below this with more info

There is no indication from what you have listed that your son displays any condition along the PDD spectrum. However, an evaluation by a developmental pediatrican does not imply anything. It is simply an opportunity to gauge your son's status along the various developmental dimensions: fine and gross motor, cognitive (including speech/language), social and emotional. The information would be interesting and useful, and there is no risk involved in arranging such an appointment. I woud regard it as a useful opportunity.

Here are things that I wonder if they are normal although I admit that most of them come from reading online & not because anyone has said anything to me when he was evaluated:
1. He loves to get different perspectives on things - let's say he's putting together his train together he will put it together & sometimes look at it from every angle while he's doing so - he loves putting things together & taking them apart - but he is not focused on only one toy.  He plays with everything.
2. Sometimes he will go around giving hugs - hugs to people he barely knows or doesn't know - laughing & playing - BUT other times he holds on to me tightly or holds onto my legs.
3. When we say his name he turns his head or comes to us; but there have been a h&ful of occasions where he has been watching a Thomas the Train & he hasn't turned his head. Although usually says uh uh to say he doesn’t want to.
4. He loves wheels but it always seems as if he's spinning them to see if he can figure out how to take them off.  He doesn't do it constantly & will do it then stop & play with a toy normally.

Any help will be appreciated.
