Back on topic after my weekend thrash of my rebuild.

Mom and I are currently wrestling with this subject.  He wants a sleepover so bad.  Everybody he has wanted to have over for a slumber party has been four years old or younger or a girl.

Whats an appropriate age to start this?  Is it OK to have boys and girls do a sleepover together at this age?

Every weekend it is a Battle Royalle on this subject.  It is a subject that must be talked about a lot in his 5 YO age group. 

This subject will not go away anytime soon.
