A crying baby is one of the biggest frustrations for new parents, but one doctor has figured out how to calm a fussy newborn — and the technique is not only quick, it's surprisingly simple.

Dr. Robert Hamilton, a pediatrician who has been practicing in California for three decades, first discovered a solution when he was looking to remedy a common challenge for professionals in his line of work: "One of the challenges pediatricians have is trying to communicate clear and precise information to their parents, a lot of times over a baby who is crying very loudly," he notes. Turns out, his method — which he coined "the hold" — is a perfect maneuver for parents at home as well.

In a helpful video, Hamilton uses his tiny patients to demonstrate the hold, which also adorably involves a little booty shaking, and then breaks it down into four simple steps:

1. Fold arms across the chest.
2. Secure the arms gently after they're folded.
3. Gently grasp diaper area with your dominant hand.
   
4. Rock the baby up and down at a 45-degree angle while shaking their booty.

This hold, he notes, is ideal for the baby's first two to three months of age, at which point they're usually too heavy to be held in such a position.

Give it a try, and tell us if it really works!
