I think that most PG kids stand out like a sore thumb although there are a few quiet exceptions. At 18 months it was obvious to everyone that our son wasn't within normal ranges.

Kids in the MG and HG ranges are not quite so easy to identify. It has to be taken on a case by case, or kid by kid basis. At 3, I would just relax and enjoy, there is lots of time to stress later!
