Hello,
My daughter had similar problems with naps when she reached this age. One thing that seemed to help was telling her that she needed to lay still in her bed and be quiet so that she could go to sleep. Part of it is teaching them how to go to sleep, and that this is what they need to do. Hang in there, it is probably just a stage and she will start napping again just like normal. Continue being consistent, even if you have to keep going in and telling her she needs to be quiet and lay down, and she has to go to sleep. I hope you find something that works, this is what worked for my daughter and we got another year of naps out of her before she cut them out almost entirely. Believe me, you don't want that yet even though some people will tell you she is phasing out the naps I believe if you hang in there it will become easier and she will nap again. Good luck.
