Andrew has started refusing to take naps. He'll lay there forever if I leave him, but he won't fall asleep. There are days when he naps, and days when he won't. The problem is when he doesn't nap, he falls apart by 4:30 in the afternoon and is that way until he goes to bed at 7. He's only 21 months, and I really don't feel like he's ready to skip out on naps, especially since he falls apart so early.
