It's been a long day. You've been fussy.
Seems like everything I've tried to quite you isn't working. I'm so tired, and you must be too, little one. You didn't have your nap today. As a last resort, I'm letting you cry yourself to sleep. Why are you so restless? You're well fed and clean. I know that in order to meet your needs, I must first meet my own. How I long for sleep. You're still crying as I write this. Does that diaper need changing? Sleep is beckoning.
