All babies cry, but sometimes a baby will cry for hours at a time, no matter what you do. This extreme type of crying in a baby between 3 weeks and 3 months of age is called colic. Although it is upsetting for parents and caregivers, colic is normal for some babies.
Doctors usually diagnose colic when a healthy baby cries more than expected: more than 3 hours a day more than 3 days a week for at least 3 weeks in a row. Colic is usually worst when babies are around 6 to 8 weeks of age and goes away on its own between 8 and 14 weeks of age.
It is common to feel scared, upset, or frustrated when you cannot get your baby to stop crying. But remember that colic is normal—and temporary. Your baby will grow out of it.
Doctors are not sure what causes colic, but it may be the result of a baby's sensitive temperament and an immature nervous system. These things may make a baby cry easily and have trouble stopping. As babies grow and develop, they are better able to control their crying.
Colic is not related to health conditions, such as digestion problems. But having gas in the belly can make crying worse.
Colic is not caused by pain or illness. If you think your baby is crying because he or she is hurt or sick, call your doctor.
Colic is not your fault or your baby's fault. It doesn't mean that you are a bad parent or that anything is wrong with your baby.
Most babies will cry less when they are held, fed, and given attention. These things may not work for babies who have colic. When they are crying, they may clench their fists and stiffen their stomach and legs. Some babies arch their back, while others pull up their legs to their stomach.
Vomiting, diarrhea, fever, or blood or mucus in the stool is not a symptom of colic. If your baby has any of these symptoms, he or she needs to be checked by a doctor.
If you are worried about your baby's crying, see your doctor or talk about it at your baby's next routine checkup. To make sure that crying is colic, your doctor may do a physical exam and ask you about your baby's past health, what comforting techniques you have tried, and whether you have noticed any other symptoms. You may also be asked about how the crying affects you and to show how you feed and burp your baby. Your doctor may suggest that you keep track of when and how often your baby cries.
If your baby has any symptoms that worry you, such as vomiting or a fever, your doctor may do lab tests or X-rays to find out what is causing them.
It may help to see if there is a pattern to your baby's crying. Many babies cry most in the late afternoon and evening hours. If you notice that your baby cries at certain times of day, you can try holding your baby more before those times. But during expected fussy times, limit visitors, keep noise and lights low, and touch your baby only if needed.
After crying starts, try rocking your baby in a quiet room, or take him or her out for a walk in a front-pack carrier or stroller. Some babies are soothed by riding in a car or listening to a droning sound, like a fan or a clothes dryer.
Do what you can to comfort your baby, but accept that sometimes nothing works. If you feel stressed or worn out, ask a friend or family member to give you a break. Take good care of yourself, and remember that colic will go away soon.
Because infants cry more in their first 3 months than at any other time in their lives, it is often difficult to tell the difference between colic and expected crying behavior. Both types of crying gradually increase, peaking at about 6 to 8 weeks of age. Most crying episodes occur in the late afternoon and evening hours, although the timing may vary. The length and intensity of crying episodes also may change from one day to the next.
The difference between colic and normal crying behavior is related to the frequency, duration, and intensity of crying. Babies with colic typically cry for more than 3 hours a day more than 3 days a week for at least 3 weeks in a row. A colicky baby cries very loudly, sometimes piercingly, and often continuously. During a colic episode, babies may clench their fists and stiffen their stomach and legs. Some babies arch their backs, and others pull up their legs to their stomachs.
Most babies with typical crying behavior are soothed and will cry less when they are held, fed, and given attention. But babies with colic are not easily soothed after they start crying. And their episodes typically last longer than expected.
Colic is usually worst when babies are around 6 to 8 weeks of age and goes away on its own between 8 and 14 weeks of age.
By definition, colic is not caused by pain or discomfort. Most likely, your baby's crying is normal. But health problems or injuries can cause a baby to cry or make a colicky baby's crying worse.
Learn ways to tell the difference between normal colic and signs of a medical problem. For example, a baby may cry more when he or she has a digestion problem such as milk protein intolerance or milk sugar intolerance. Some mothers also say they notice their baby's crying gets worse after they have had certain foods or drinks and then breastfeed. Some foods may affect breast milk, such as garlic, broccoli, fresh fruits, and caffeine. They may contribute to intestinal gas or other digestive problems in the baby.
After your baby has started to cry, use comforting and soothing techniques to try to shorten the episode or decrease its intensity. Certain preventive measures may also help. Colic gradually goes away on its own, regardless of what you do.
Keep a diary to chart your baby's daily activities, including when he or she cries. The record may help you to notice patterns in your baby's crying and increase your ability to predict when colic episodes are likely to occur. You may be able to help prevent or decrease crying episodes during those times:
Colic is not caused by health problems. But when your baby doesn't feel good, crying episodes may get worse. You can help minimize colicky behavior by taking preventive measures to reduce your baby's risk of illness.
After a colic episode begins, comforting measures may help.
If you find that you are losing patience or are afraid that you may hurt your baby, act immediately.
Call your doctor if you frequently feel overwhelmed or are unable to get adequate support.
Do not use unproven or dangerous treatments for colic. Get advice from your doctor before using alternative therapies, which may have unknown effects.
Also, be careful about acting impulsively or using desperate measures to treat colic. For example, do not:
Some doctors prescribe probiotics, which are bacteria that help maintain the natural balance of organisms (microflora) in the intestines. Studies are being done to find out how helpful probiotics are for babies who have colic.
It is important to take care of yourself and remember that colic is not caused by poor parenting. Colic is temporary, and it will not affect a baby's general health or future development.
If nothing seems to console your baby, keep trying comforting techniques, but realize that sometimes nothing works. If you are not successful and you become exhausted by these efforts, ask for someone else to take over for you.
Call 911 or other emergency services immediately if:
Call your doctor immediately if your baby:
Call your doctor and schedule an appointment if:
Also, think about your own health and well-being. Call your doctor if you:
The following health professionals can examine your baby and diagnose colic or other conditions that may be related to excessive crying. They can also help you handle the common frustrations of having a colicky baby.
You can ask your doctor about your concerns regarding your baby's crying during regularly scheduled well-baby visits. But don't hesitate to call and discuss your concerns at any time. This is especially true if comfort measures keep failing or if you notice other symptoms along with the excessive crying.
At the checkup, your doctor will want to find out whether your baby has colic or whether crying is possibly related to an illness, an injury, or a medical condition. To find out, your doctor:
If the baby cries excessively and has other worrisome symptoms (such as vomiting, diarrhea, blood or mucus in the stool, or fever), lab tests or X-rays may be done to help the doctor find out whether a condition other than colic is present.
