The thing that helped me overcome my doubts about skipping my DS from K to 2nd was my own experience. I was also one of those kids who spent my elementary life hiding. I didn't feel accepted until I skipped 7th grade and started attending a GT school. Suddenly, I had friends! I am not athletically inclined, but I still managed to letter in swimming.

Your DS is who he is. Skipping would not make him different, he is already different.

Have your DH read A Nation Deceived and Genius Denied. Give him some time to think about it.
