The "Avaloran Lullaby" is a song sung by Princess Elena in the Elena of Avalor episode, "Island of Youth". When Esteban, as a baby, begins to cry after Elena rescues him from falling she calms him down by singing to him a lullaby.
Evening is a-falling, so rest your weary head
Don't cry little baby, sleep tight in your bed
The jaquins are a-nestling, way up in the trees
The scent of springtime flowers floating on the breeze
The full moon is a-shining in the sky above
Hush now little darling, bundled up with love
