Ok, up until this week, M (23months) has been really obvious when she needs a nap. She'll get cranky, get put down, and go to sleep for 1-2hours. And this week today especially, i put her down (stayed with her obviously) and she just wouldn't sleep. But if she's on a long car trip she will sleep.
I'm wondering though, if she's at that age where she is starting to give up her daytime sleeps. Or chalk it up to the fact that we've had a few rough weeks?
