Ok here goes..lately we've had a few scraps between the girls over the realm of upstairs.
As you all know Elsa is VERY timid, yet she seems more confident when shes loafing around upstairs..and lately she has become very possesive over upstairs and whenever Clementine comes up the stairs Elsa is there doing her infamous thunder-bum grumble and the fur has begun too fly.
It doesn't seem an issue of great impact just yet..but i don't want this to turn into WW3-battle for the landing

So any ideas on how too stop Elsa being so terrortorial upstairs?
