I skipped 2nd grade because my 1st grade teacher had let me do all the 2nd grade work during my 1st grade year. The skip was fine in elementary school, but I was socially behind during junior high and had a lot of emotional issues during the ages 11 - 14.

Ds7 could possibly benefit from a skip, but I am worried that it might further isolate him socially from his peers. We'll see.
