It never ceases to amaze me that most kids under the age of 5 that I've been around have an identical reaction moments leading up to their nap time. They fuss, sometimes scream, cry, throw things, and the last thing they want to do is lay down to sleep. If they only knew how good naps actually feel... I figured I'd compose a checklist for us, whenever we're feeling cranky:
drink some water
meditate
take a nap
Repeat as necessary.
