This one's set after the War of the Ring, after the hobbits learned of the dangers in the world, but also that the worst of those dangers had been defeated forever.

Hobbit Lullaby

Hush, don't worry about the night-time sounds,
The Bounders are doing their rounds.
There's no food, but no need to cry,
in the morning, the grocer will be by.

Each day is a new start,
for a babe, quickly growing up so smart.
Sleep, now's the time to dream of fun,
Tomorrow's games in the spring-time sun.

The danger's passed, your family's safe,
you'll grow up with a good life.
The new things you'll learn, showing us all how.
Sweet dreams for now.

Dream away the starlit night,
until the morning's new dawning light.
