How to help calm your newborn using Dr Harvey Karp’s gentle approach

If you are wondering why your baby becomes difficult to settle during certain parts of the day, especially in the late afternoon or evening, you are not alone.

The world outside the womb is loud, bright, and unfamiliar. Babies often need extra help adjusting in the early weeks.

Dr Harvey Karp, paediatrician and author of The Happiest Baby on the Block, developed a simple method to help soothe unsettled newborns. It is called The 5 S’s, and it works by mimicking the familiar sensations of the womb.

Here is what they are and how to use them.

What Are The 5 S’s?

These five techniques are designed to activate your baby’s calming reflex, which is a built-in way their body settles in response to gentle stimulation.

They often work best when used together, but even trying one or two can be helpful when your baby is fussy or overwhelmed.

1. 

Swaddling

Swaddling is the practice of wrapping your baby snugly in a lightweight blanket to help them feel secure.

It reduces startling and helps babies settle by recreating the contained feeling of the womb.

Make sure the wrap is firm but not tight, with room for hip movement.

Always stop swaddling when your baby begins to roll.

2. 

Side or Stomach Position

 (for soothing only, not for sleep)

Holding your baby on their side, on their stomach along your forearm, or in a tummy-down cuddle hold can reduce crying.

This is because it engages calming reflexes and may help with wind or colic.

Important note: always place your baby on their back to sleep. Use side or stomach holding positions only when they are awake and in your arms.

3. 

Shushing

Your baby is used to loud whooshing sounds inside the womb.

A strong, steady “shhh” sound can help block out external noise and promote calm.

You can do this with your voice, or use white noise from a safe machine or app.

Keep the sound consistent and close to your baby’s ear, but not too loud.

4. 

Swinging

Gentle motion can be very soothing for babies.

In the womb, they were rocked constantly as you moved around.

Try swaying side to side, walking while holding them, using a rocking chair, or doing soft bouncing movements while supporting their head and neck.

Avoid fast or rough movements.

5. 

Sucking

Sucking helps babies feel safe and calm.

This can be through breastfeeding, a clean finger, or a dummy if you choose to use one.

It is not just about feeding, it also supports regulation and comfort.

Why These Techniques Work

Your baby spent months in a warm, moving, noisy environment where they were held and comforted constantly.

The 5 S’s recreate that feeling in a way that helps your baby relax and feel secure.

These methods are especially helpful during the evening fussy period, times of overtiredness, or when your baby is working through wind or discomfort.

A Gentle Note

Not every baby responds the same way.

Some love swaddling, others prefer movement or sucking. You do not need to follow a formula, just try what feels right.

These techniques are tools, not rules. Use what helps you both feel more calm and connected.
