The 5 S's That Calm a Screaming Newborn in Minutes

There's a moment every new parent hits: the baby is screaming, you've checked everything, and nothing is working. The 5 S's—a method popularized by pediatrician Dr. Harvey Karp—are designed for exactly this. They recreate the snug, noisy, motion-filled environment of the womb and trigger a newborn's natural calming reflex. Done together, they can settle a crying baby surprisingly fast.

This is general education, not medical advice. Never shake a baby—see the safety note below. If crying is inconsolable or comes with other symptoms, call your provider.

First, Run the Checklist

Before soothing, quickly rule out a clear need: hungry? wet/dirty diaper? too hot or cold? uncomfortable? unwell (fever)? If there's an obvious cause, address it. The 5 S's are for the times the baby is fed, dry, and well, but still crying.

The 5 S's

1. Swaddle

Wrap your baby snugly in a thin blanket, arms in, to recreate the containment of the womb and stop the flailing startle reflex that wakes and upsets them. Keep it firm around the arms but loose around the hips (hips need room to move for healthy development).

2. Side or Stomach Position

Hold your baby on their side or stomach in your arms (or over your shoulder)—this position often calms a fussy baby. Important: this is for soothing while you're holding them, never for sleep. For sleep, babies always go on their back.

3. Shush

Newborns aren't used to silence—the womb was loud. Make a strong, continuous "shhhh" sound right near their ear, or use white noise (a steady, womb-like sound). It needs to be as loud as the crying to start, then you can lower it.

4. Swing

Use small, fast, jiggly motions (always supporting the head and neck)—tiny movements, not big swings. Rhythmic motion is deeply soothing. Think a gentle, fast jiggle rather than a wide rock. Never, ever shake the baby (see below).

5. Suck

Sucking is calming. Offer the breast, a clean finger, or a pacifier. The act of sucking can switch a baby from upset to settled.

Stack Them Together

The magic is in combining them: swaddle, then hold on the side, with loud shushing, a gentle jiggle, and a pacifier—all at once. One alone may not do it; layered together, they're far more powerful.

A Critical Safety Note

The "swing" is a gentle jiggle while fully supporting the head—never a shake. Shaking a baby can cause devastating, life-threatening injury (abusive head trauma). If you ever feel overwhelmed, frustrated, or at the end of your rope with a crying baby, it is always okay to put the baby down safely in their crib (on their back) and step away for a few minutes to breathe. A crying-but-safe baby is fine while you reset. Never shake a baby, ever.

When Nothing Works

Some crying just has to run its course—this is normal, and there's a known pattern of normal increased crying in the early weeks (sometimes called the "period of PURPLE crying"). It peaks and then improves. But call your provider if crying is inconsolable for long stretches, sounds different (high-pitched or weak), or comes with fever, poor feeding, fewer diapers, vomiting, or lethargy.

The Bottom Line

When your newborn is screaming and fed and dry, the 5 S's—swaddle, side/stomach hold, shush, gentle jiggle, and suck—recreate the womb and trigger their calming reflex, especially stacked together. Soothe on the side but always sleep on the back, never shake, and put the baby down safely and step away if you're overwhelmed. Most of the time, the 5 S's turn the volume down fast.
