Have you ever felt like your baby is fighting sleep? You’re certain they’re exhausted, and yet, no matter what you do they just won’t give in to sleep. In fact, you know with certainty your baby just needs sleep. Frustrated, you let out an audible sigh and return to shushing and rocking, despite the dull ache in your weary muscles. Finally, after an hours-long battle of wills–or was it days?–your little one finally crashes into sleep. You put them down, certain they will sleep for hours after all of that effort, but within minutes, they’re up again crying for your help.
