One suggestion I have is to see if your local school district does 0-3 developmental screening. This is a free assessment carried out by professionals (speech / OT / special ed). If they have any concerns, your ds should qualify for special services through the district. Child psychiatrists often don't have a lot of experience with very young kids and can be biased toward pathology (I would still keep your appt...but just get this second opinion).
I have had to keep most of my ds' precocity to myself ...it can be lonely. I am fortunate that one of my friends (a former teacher) knows about GT kids and has been pushing us to recognize my ds as gifted. I finally feel like I can talk in RL about the benefits and drawbacks of my ds' advanced abilities.
