to calm down
Te convendría calmarte así no terminas muy agotado, Ben.
You'd do well to calm down so you don't end up completely exhausted, Ben.
— La canción del mar (2014)
You have to calm down.
Debes calmarte, de otra forma Mommy no podrá ayudarte.
You need to calm down, otherwise Mommy won't be able to help you.
— Mommy (2014)
