To nap or not to Nap, that is the question?

My sweet little Eliza. I have to say I love every second of her even though she is now making messes everywhere she goes. She loves to draw on herself and tell me how pretty she is. I need to chronicle one solid week and I'm sure I can come up with at least 5 masterpieces. When she finds the sharpies, it is the best. Anyway, I love her nap times and she sleeps for a good 2 and half hours when I get her down. But, when she naps she is up until at least 11 at night (way past my bedtime) so...there are times we decide to do the no nap thing. She does not get crabby at all but we do get this at dinner time every once in awhile. So sweet. The kids thought it was hilarious.
