Bed time wars

We are working on getting the grand kids to bed.  It is a matter of being persistent, but it does wear on the temper.  The gambits this evening have been not wanting to sleep in the bed Wyatt was put in.  Hiding in the corner of the bedroom.  Asking for numerous bed time stories, and finally coming downstairs naked with a new diaper in hand.  I might add that there was nothing damp with with old diaper.  Everything is delaying tactics, just to see who can outlast the other.  So far I am betting on Ray and myself, but it isn't easy.
