Hi Gail, I wonder if you need to abandon the nap in her bedroom? My Spirited one totally refused to nap from 2-2.5 (totally dropped by 2.5) but would fall asleep on the sofa with cuddles and a DVD on. Not ideal I know, but it was the only way to get him to stop!
So we would have lunch, stick a DVD on, get a cup of tea and just cuddle. Actually we still do on a lot of Saturdays after a busy week and a morning at swimming. If he slept, all good, if not he had at least had a rest.
