Always follow safe sleep guidelines and consult with your pediatrician before making any changes to your baby's sleep position.

Owls sleep sitting upright, when perched on a branch or the like. They hunch their heads down between their shoulders, sometimes their beaks tuck into their neck or chest feathers.
