Soothing Techniques That May Help

What Doesn't Have Strong Evidence

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.
