The transition from 1-0 can be very long winded!! Ds dropped her actual nap, but frequently gets to bout 3pm and then drops to sleep wherever she is (car, stroller, carpet) and is pretty unrousble for at least 15 mins. That said, late naps result in a late bt and often an ew. Grrrr!
I think the ideal at this age would be a 12 hour day and 12 hour night.
