There is a huge difference between parents who choose to have their children co-sleep, and kids who will not stay in their own beds.
TO ME, these sound more like tips for helping a child who is scared/anxious about the dark, or who is transitioning into a bed (from crib or from parents' bed).
Use (or not) as you'd like!
