Sorry to say, but it sounds like your daughter is done with naps. What you can do is have "quiet time" where she can play quietly in her room. She has to stay in her room unless she needs to use the potty. After all, we don't want pee on the floor!
My 5 year old's nap routine is I read her a book. Then she does quiet time and I take my nap. Meanwhile, my youngest (2 years old) takes her nap. Quiet time is finished when my youngest wakes up. After all, my nap is done, too! I've found that although my oldest doesn't need a nap, she does need time to play on her own. If she doesn't get it, she can get grumpy. We started this routine when she was 2.5 since she wasn't a napper at all and I needed a nap!
