...an acceleration, if one grade will most likely not be enough?
That is the only reason I would have a child skip a grade. If a one grade acceleration was enough to accomodate my child, then I would probably pursue other options. That would not be enough of a need to me to outweigh the cons of a grade skip.
To me, a one grade acceleration would be part of a "program" consisting of future whole grade accelerations, subject accelerations, curricula compacting, enrichment, etc., that would be necessary for a child that was really advanced. The one grade skip would be a stepping stone, not the end goal.
As to your child's needs, I couldn't say of course since I don't know him. But as far as recess and lunch being the favorite parts of the day, I have several children, ranging from normal-ish to really advanced, and they all liked lunch and recess best. That might just be part of being a kid.
