Since naps and bedtime are so peculiar, I tried something else today.
We did a combination of tiring her out by strolling and going to the playground, etc.
Since she didn't show signs of sleepiness and didn't express her desire to go to bed and literally have another slumber party with Mommy, we opted to see if following her cue to not nap would reset her.
She is hollering for bed now. Keep your fingers crossed.
