Consoling a baby who cries a lot for no known reason is tough. Learn ways to care for the infant and cope with the stress.
Update Date: 20.12.2025
Colic is when a healthy infant cries often, long and hard or is very fussy. Colic upsets parents because their baby's distress happens for no known reason. And no amount of consoling brings relief. Colic often happens in the evening when parents are likely to be most tired.
All babies cry more during their first 3 months than at any other time. If a baby has colic, most often it's at its worst when an infant is about 6 weeks old. The bouts of colic lessen after 3 to 4 months of age.
But even though the crying calms with time, managing colic adds stress to caring for a newborn. You can take steps that may lessen how bad bouts of colic are and how long they last. This also will ease your own stress and make you feel better about your parent-child link.
Babies fuss and cry, mostly during the first three months of life. It's hard to say what's typical. Mainly, colic is defined as crying for three or more hours a day, three or more days a week, for three or more weeks. But you don't have to wait three weeks to seek help.
Features of colic may include:
Bouts of long, loud crying that can't be soothed may be colic. Or they may be a sign of a condition that causes pain or discomfort. Make an appointment with your child's healthcare professional if your infant has symptoms of colic.
The cause of colic is unknown. Many factors might be a part of colic. But researchers don't know why it most often begins late in the first month of life, how it varies among infants, why it happens at certain times of day and why it resolves on its own in time.
Some factors that might be a part of colic include:
Risk factors for colic are not well known. These factors have not been shown to increase risk:
Some studies have shown smoking to be a factor. Infants born to someone who smoked during pregnancy or after delivery might have an increased risk of colic.
Colic that goes away before 6 months of age does not cause short-term or long-term medical problems for a child.
Colic is stressful for parents. Research has shown a link between colic and the following for parents:
The stress of calming a crying baby has caused some parents to shake or otherwise harm their children. Shaking a baby can cause serious damage to the baby's brain and death. The risk of harming the baby is greater for parents who don't know how to sooth a crying child, haven't learned about colic and don't have the support they need for caring for an infant with colic.
Your baby's healthcare professional will ask for a detailed history and do an exam to diagnose your baby's colic. The healthcare professional will:
Lab tests, X-rays and other diagnostic tests often aren't needed. But if it's not clear that the baby has colic, tests can help rule out other causes.
The goal of treatment is to find ways to soothe the baby as much as possible and make sure parents have the support and information they need to cope. As a parent, learn all you can about colic. That way you'll know it's common and not your fault.
You may find it helpful to have a list of ways to soothe your baby. You may need to try more than one way. Some ways may work better than others. Some may work one time but not another. Some things to try:
Changes in the way you feed your baby also may give some relief. Stick to either feeding your baby on demand, which is when the baby is hungry, or on a fixed schedule.
Hold your baby upright while bottle-feeding. Burp the baby often during and after a feeding. Use a curved bottle. A bag that caves in as it empties can reduce the intake of air.
If soothing attempts or changes in feeding practices don't help the crying, your baby's healthcare professional may suggest a short-term change in the baby's diet.
Changes in the diet may include:
Caring for an infant who has colic can wear down any parent. To help you take care of yourself and get the support you need, try to:
One factor that may add to colic is that the good bacteria in an infant's gut is out of balance. One treatment being studied is the use of good bacteria, called probiotics. Probiotics might help the bacterial balance to improve overall gut health.
Some studies have shown less crying time when babies with colic were treated with a bacterium called Lactobacillus reuteri. The studies have been done with small groups, and results have been mixed. Most experts agree that the study results don't support the use of probiotics to treat colic at this time.
Several small studies have shown some benefits or mixed results for alternative treatments. But there's not enough evidence to judge the potential benefit over the risks. Alternative treatments being studied include:
Known risks include the following:
Talk to your baby's healthcare professional before using any alternative medicine.
Here's some information to help you get ready.
To prepare for your appointment, make notes about:
