My four children have never been great sleepers. It began when the first child was born and decided that there was so much more to life than sleeping. That message was passed along to each of her three younger brothers and left me absolutely exhausted.
I would call my mom and complain and she would say,
"Bring them to Kentucky. They'll sleep here."
We would pack up and spend the day traveling and when we arrived I would warn again,
"They never sleep through the night."
My mom would cuddle up with her grandbabies and begin to rock, and then sleep would win.
And, yes, they always slept through the night.

Those babies are well on their way to growing up now, but they still say there's no sleep as wonderful as a Kentucky sleep.
