My mum tells the story of my brother born at 36 weeks, he wouldn't give her 2 naps at just before 12 months and she had to start only giving him 1 nap, I on the other hand was born at 40+4 and I took 2 naps until past 18 months and my eldest didn't go to 1 nap until 20 months... So the personal variables do come into play.
