The pediatrician we have for our children is about 60 years old and is nearing retirement. He has seen literally thousands of kids grow up.

When DS was a few weeks old and we took him in for a routine checkup, our pediatrician told us that "We won't need to save any money for college. He is extraordinarily bright." He said that based upon his opinion that our son was unusually alert. We didn't take it seriously at the time.

Later, when DS was 2 years old and we were concerned he wasn't speaking, our pediatrician told us that he had no worries whatsoever, and that when DS finally "decided" to speak, it would be in full sentences. A few months later, DS did start speaking, in full sentences as predicted.

And he still has the same unusual level of alertness, and we still get comments about it from random people.
