a couple of times when i could not get out in the rain (this happened with both girls) i put her in the pram and covered it up and pushed it around in the apartment/house (she did not know we had not gone out, but the motion and change of location did the trick and i got the nap in and we got back on track for the day) i have done this when at friends' houses and alex woudl not nap in the porta-cot.
