Infant colic

Babies who suffer from infant colic will cry and fret inconsolably for several hours or more at a time, without an obvious reason.

Key points

  1. Infant colic is persistent crying, often for several hours and without an obvious cause, in otherwise healthy young babies.
  2. Colic mostly affects infants between two weeks and 16 weeks of age.
  3. Infants usually grow out of colic and it is not considered dangerous, though can be very stressful to manage.
  4. Follow the advice of your doctor, nurse and Plunket. You can also contact Healthline if worried about your child.


Babies who suffer from infant colic will cry and fret inconsolably for several hours or more at a time, without an obvious reason. They may clench their fists and draw their legs up to their tummies. The colic often occurs in the late afternoon or early evening and usually will happen at the same time of day or night. Sometimes the colic may end with the passing of a bowel motion or gas, or the child may simply cry him or herself to sleep.


The cause of colic is unknown. Colic is not considered dangerous, although it can be frightening and difficult to deal with. Sometimes other conditions such as reflux or lactose intolerance may be involved, but with colic the baby is otherwise thriving and healthy.

How can I help my baby?

The management of infant colic is very difficult. It often seems to be at its worst when parents are tired and overwrought themselves. There is no sure-fire cure for colic and most babies will outgrow it by around 16 weeks of age. Some tips to help you and your baby cope with colic:

  • Be prepared. If the baby is likely to require your undivided attention for several hours in the evening, plan to keep those hours free for him or her. At the time it may seem that it will never end, but feel confident that it will pass! Be creative, the rest of the family can eat tea and have baths at 3pm for a few months.
  • Resist the temptation to find something on which to blame the colic. Colic has been a problem for babies (and parents) for many years, with no cure being found.
  • Look after yourself. Eat a nourishing snack before an anticipated crying period.
  • Maintain breastfeeding on demand. If the baby seems worse after certain foods are eaten by the mother then it may be wise to exclude them. It is not necessary for the mother to change her diet otherwise.
  • If the baby is bottle fed, check the formula is made up correctly. Stop the baby once or twice during the feed to burp him or her. Discuss with your Plunket nurse or doctor whether you should change the brand of formula you are using.
  • Buy or borrow a carrying device such as a front pack or sling in which to carry your baby. This allows you to get on with some activities.
  • To reassure the baby with colic, hold or carry him or her as much as you can. Play soothing music and keep the lights dimmed. Handle the baby smoothly and speak quietly.

Ask for and accept offers of help – caring for a baby with colic is not a one-person job.
