MrsJamin - Pre-DS I would have agreed with you entirely, but the only place I could get him to nap during the day was in the aquarium equivalent of this swing (which had an active rocking action and a shushy-shushy white noise setting). Up until eight weeks he just didn't nap apart from literally fifteen minutes at a time, but if I swaddled him and jiggled him to sleep I could put him in the swing for a couple of hours. It quite literally saved my sanity, and as he never went in it when awake I think he avoided overstimulation. Mind you, I've not got it out of storage for DD as she naps OK and I haven't seen the need.
