To tell the truth there have been some teething problems with the new sleeping arrangements. Not least of which is E5N1 getting out of his bed and disturbing his sisters:
Maybe we should have gone with plan A and left Exile #3 in her own room, moved Exile #4 into the guest room (except for when we have guests of course - do come and visit!) and moved E5N1 out of his crib/cot into the toddler bed.
Maybe we did.
