I have 4 children and they are all different. My second did not require a lot of sleep. Just after he turned 2, he put himself on and every other day nap schedule. I knew he wasn't ready to go "cold turkey", but we did have down time. It wasn't at his normal nap time though, it was later in the day. This worked out because if it looked like he was going to sleep, I would tell him he needed to help me and I would give him little things to do. (get out a potato for dinner, get the dog bowl to feed him) He also knew when he was sleepy and sometimes he would lay on the floor, play with his cars and fall asleep. I would leave him there and when my older one was up from her nap, I would let her play around him. At 3, he knew if he was tired to go to his room where he would not be bothered. Kids are smarter then we give them credit for. Yes, I would guide him by telling him, if he woke up and was mad at his sister for making too much noise, that if he were in his bed he would not hear her making noise. He gave up his naps completely by age 4, but also went to bed earlier at night. My oldest took naps until she was almost seven, just short ones but long enough to get her through the day. The other 2 took naps until they were 4, and one of them only because she was in the car with me making my rounds of getting her siblings from school. Actually, she would fall asleep at least 2 days a week when she started full day kindergarten and she had nap time. Good luck!!! I hope she gets a nap schedule down for you. But be patient and gently guide her into what you feel will work out best.
