APOP = accidental parenting on purpose. Basically using every trick in the book to get LO to sleep, so holding, rocking, bouncing, car, pram, whatever it takes. The idea of AP (accidental parenting) is what Tracy Hogg warned us against in her BW books, as habits build and we don't want bad habits and props, however doing it as a planned thing for a short nap can sometimes help in the short term when routines are changing. The "bad habit" doesn't matter so much as the CN drops anyway and when it drops the bad habit drops with it.
