Lullabies for Colic & Fussy Evenings

When nothing seems to work, a slow, steady lullaby can become part of one of the most researched calming methods for crying babies: the “5 S’s.” Here’s how it works, and how to use it tonight.

The method

The “5 S’s,” and where lullabies fit in

Developed by paediatrician Dr. Harvey Karp, these five techniques work together to recreate the constant, rhythmic sensations of the womb.

Swaddle. Wrap your baby snugly (stop swaddling once they show signs of rolling, usually 2–4 months) to recreate the snug feeling of the womb.

Side or stomach position. Hold your baby on their side or stomach in your arms while awake — never for unsupervised sleep.

Shush. A loud, steady “shhhh” or continuous, rumbly sound — this is exactly where a slow, unbroken lullaby can take over from your own voice.

Swing. Small, rhythmic motion (never vigorous shaking) mimics the constant movement babies felt in the womb.

Suck. A pacifier, clean finger, or feed can help trigger your baby’s natural calming reflex.

Why this matters for lullabies: the “Shush” step works best with a continuous, low, rumbly sound — not a hissy fan or ocean app. A slow, steady, handplayed lullaby on repeat can serve exactly this purpose while also building a long-term sleep association.

One more idea

Combine movement and music

Research has found that carrying a crying baby while walking can noticeably reduce crying compared to holding them still. Pairing that gentle movement with a continuous, low lullaby — walked, swayed, or rocked in rhythm with the music — combines two of the most evidence-backed soothing techniques at once.

Frequently asked questions

What’s the difference between colic and normal fussiness?

Colic is typically defined as crying for more than 3 hours a day, more than 3 days a week, for more than 3 weeks, in an otherwise healthy baby. If you’re concerned, speak with your pediatrician.

Why does “shushing” work?

It’s thought to mimic the loud, constant whooshing sounds of blood flow babies hear constantly in the womb — a familiar, comforting backdrop rather than silence.

Can I use the 5 S’s together with a lullaby?

Yes — many parents find combining swaddling, gentle motion, and a steady lullaby (instead of a hand-shushing sound) works especially well once it becomes a consistent routine.

When should I call a doctor about crying?

If crying seems unusually intense, is accompanied by fever, vomiting, or feeding difficulties, or you’re finding it hard to cope, contact your pediatrician — colic-like crying can sometimes have an underlying medical cause.
