Hi L.
No, she is not too young to outgrow her naps, both of my kids stopped napping at this age, but they do need about 12hrs of sleep at this age, so my kids go to bed around 7/7:30 and sleep about 12 hrs. Some parent's give me a hard time for putting them to bed so early, but they fall asleep right away and it is nice to have the whole day to do stuff with them without having to be home for naps.
Good luck
