My twins were on the same schedule! They are 3 now, and still napping, but I have to cap it in order to get a reasonable bedtime! At 2.5 years, I did exactly what pp said- nap at 1 and only for an hour and a half! We are still doing the 1pm nap now, but it can only be for an hour. I am basically only letting them be in their cribs (yeah, don't want to tackle that just yet
from 1-2. If the fall asleep then bedtime is 7:30, if they don't, or only for a short amount of time (DD sometimes does this), then I just move bedtime up. Good Luck!
