As a child, my mother sang this version of Eugene Field's Wynken, Blinken & Nod to my siblings and me.  The lilting tune will put you to sleep if you fall asleep to music!  It mimics the rocking of a boat, which is appropriate for this sea-based poem.
This was my firstborn son's favorite lullaby.  I've sung it hundreds & hundreds of times!  Here is my acapella lullaby version for you or your child.   
This is also one of the poems in Ambleside Online's Year 2 curriculum (term 2:  
Eugene Field).  
Enjoy!
