The main reasons to accelerate would be to have more time with older peers and more challenging material. The main reasons not to accelerate would be fine motor issues and nap issues (the kindergarten group does not have a real nap time).

Right now I am leaning against - mainly for the nap reasons. DS still needs to nap. Heck - most days I would not mind taking a nap.

He will be participating part time in a gifted pre-k program (4hr/day x 3 days/week) so I am hoping this is enough of a safety valve to make the kindergarten acceleration unnecessary.
