Hmmmm... my DS wanted the skip but he hadn't been at the school long enough to form any real friendships.

Our school is so large that the chances of being in the same class with a friend are only 1 in 6 anyway. DS can still play with his friends from K at recess, too.

What if you make plans to invite friends over for playdates more often? They would have more time to interact on a playdate than they would in class anyway.
