Hi there,
My daughter turned 2 in November and for the past 2 months she sometimes naps and sometimes she does not nap. She is now in a toddler bed because she was climbing out of her crib. If she is tired enough then she will nap but if not she plays in her room. I leave her in her room for at least an hour and half, if she is not tired enough then she at least needs some alone time and so do I !! If she doesn't nap then yeah she can be a pain in the evenings, but then I just put her to bed a little early.
I don't have any good advice, I would just continue to put her in her crib to nap and leave her like normal....that way she knows that she is going there no matter what and see what happens. I agree they are TOO YOUNG still to give up a nap...everyone needs the quiet time. Just don't give up....keep up your routine when putting her to nap and she will learn that she is going to be in her crib wether she naps or not. Maybe put a few toys in there and she can play for and little and then when tired enough go to sleep.
Hope I helped a little....you are not alone with this battle you are doing GREAT!!!
