Step 18 = Hang up PJs to air.
Pyjamas should be aired every day (not just stuffed under a pillow to remain a sweaty haven for smelly bacteria).
Make PJ-care part of the morning routine by ensuring everybody has hanging pegs that they can reach. Dressing-gowns need a designated home too, or they end up annoyingly snagging and dragging on too-low-for-them door handles or sitting in a stinky pile in the corner of the bedroom.
