"Breathe Easy" is a Doc McStuffins song from the Season 3 episode "Winded Winnie". It is sung by Doc, Stuffy, Lambie and Hallie. In this song, Doc, Stuffy, Lambie and Hallie sing to Winnie the Tiger about calming down and not to breathe badly.
Take three breaths
Deep and slow
Tell a grownup who knows
How to keep you calm
If you're sneezy and you're wheezy
Your breathing won't come easy
Stay calm and cool
If you feel panicky
If your breath has trouble moving
Slowing down can be so soothing
Breath long and deep on one, two, three
Until it's easier to breath!
