The 'Rule of Three'
Colic is traditionally defined as crying for more than 3 hours a day, on more than 3 days a week, for more than 3 weeks, in an otherwise healthy, well-fed baby. Crying often occurs in the evening and can seem inconsolable.Soothing Techniques That May Help
- The '5 S's': Swaddling, Side/stomach position (while awake and supervised), Shushing sounds, Swinging/gentle motion, Sucking (dummy/pacifier)
- White noise or vacuum cleaner sound
- Warm bath
- Gentle tummy massage or bicycling legs (for suspected wind/gas)
- Taking turns with a partner or support person — parental exhaustion is real and valid
What Doesn't Have Strong Evidence
- Anti-colic drops (simeticone) — evidence is weak/inconsistent
- Switching formula repeatedly — not usually helpful unless cow's milk protein allergy suspected
- Herbal remedies — limited evidence and safety data in infants
When to See a DoctorIf crying is unusual for your baby, associated with fever, poor feeding, vomiting (especially green/bile), blood in stool, reduced wet nappies, or if you're worried something is wrong — always trust parental instinct and seek medical review.
Take Care of Yourself TooPersistent infant crying is one of the most stressful experiences for new parents and a known trigger for parental burnout and, rarely, harm to the baby. If you feel overwhelmed, put the baby safely in the cot and step away for a few minutes. Call a support line or a trusted person for help — you are not failing.
Is colic caused by something I'm doing wrong?
No — colic is not caused by parenting, and there is nothing you're doing wrong. It occurs in babies regardless of feeding method or parenting style.
Does colic mean my baby has a digestive problem?
In most babies, no specific cause is ever found. A small proportion may have cow's milk protein allergy or reflux — if colic is severe, worsening, or associated with other symptoms, discuss this with your GP.
When does colic end?
Colic typically peaks around 6 weeks and resolves by 3–4 months in most babies, as their digestive and nervous systems mature.
