If you think lullabies are only effective for getting little ones to drift off to dreamland, think again! Turns out they work wonders on gentle giants, too.

In this heartwarming video, Sangduen “Lek” Chailert, founder of the Save Elephant Foundation in Thailand, embraces and sings to an elephant that has taken a particular liking to her. Though Faa Mai is massive compared to the petite woman, she loves nothing more than nap time snuggles and the soothing voice of Lek. It’s a bond so magical you have to see it to believe it.

The peaceful look on that gentle elephant’s face might just be the sweetest thing I’ve ever seen. Every elephant deserves to be just as happy and loved.
