When do you throw in the towel and proclaim that a nap is not happening?
My son has been in his crib since 12:30. It's 1:35. He's not napping. He jabbered for a bit. Then cried. Then kicked his crib slats. Then cried more. Now jabbering again. He's been up since 6:35. He's 15 months old, not 4 years old. WTF?
