This hits home today as we had his three year old checkup with his doctor today. They gave me the little "what is your child doing" checklist and when the doctor saw it he actually laughed, and then turned and said "can you really spell" to my DS.
Most doctors will never see a toddler that advanced. Its one thing to see a bright kid, its another to be confronted with it.
Our Pediatrician recognized that Mr W was unusual from the very beginning and has been sympathetic to his situation. She spent some extra time with us at his 1 year to talk about how unusual he was.
