We consulted a Pediatric Developmentalist for both of our children just to make sure things were on track (we had some concerns). She was recommended by someone I spoke with from the GDC, and we felt it was well worth it. She is a pediatrician with extra training in developmenal disorders, and sees quite a bit of autism in her practice. She also sees a lot of giftedness in her practice as well, which put us at ease because she "gets" that these kids can have all kinds of stuff going on that is fairly typical in the gifted set and isn't necessarily worrisome within that group.
From there, we received a report that detailed her findings, her suggestions for assessments from different areas of practice (OT, WISC-IV testing, therapy, and so on), and suggestions to help with some things that didn't require intervention. For example my youngest had really high visual perception skills, but his mechanics tested right at grade level so she suggested we teach him to type, scribe for him, continue homeschooling, etc.
