DS (3) still has naps. Both my kids are nappers. Even on the days when he would fuss and not sleep I still made sure he had quiet time in his room. Some days he sleeps others he doesn't but he still has quiet time in his room. DD 7 can still have a nana nap if we're all having one. She loves her naps and I'm sure if school allowed it she'd opt for one at school too LOL!

Every kid is different, and if you're ok with her dropping her nap then I wouldn't worry if you want it to still be an option then just push through with it, knowing some days she may nap others she may not.
