Topic Overview

What is colic?

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

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.

What causes colic?

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

What are the symptoms?

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.

How is colic diagnosed?

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.

What can you do about colic?

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.

What to Expect

Similarities and differences between normal crying and colic

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
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

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

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.

Other problems that can cause crying

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.

Home Treatment

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

  • Anticipate your baby’s needs. Pay attention to your baby’s natural habits and set a rough schedule for meals,
    nap, and play. That way, you can predict behavior and respond appropriately.
    You may also want to try holding and comforting your baby before his or her
    usual crying time. Use a front carrier or sling so you can do other things
    while you keep your baby close to you.
  • Create a calm environment. During expected
    fussy times, touch your baby only if needed, and try to limit visitors, bright
    lights, loud noises, and chaotic situations. Overstimulation can trigger a
    crying episode or make one worse.
  • Reduce stress. Babies are very sensitive to the
    moods of their caregivers and may cry more during times of family
    stress or tension.
    Take good care of yourselves to help keep your baby’s environment calm and
    safe. Remember that this challenging time won’t last, and know that you have
    personal limitations.
  • Ask for help when you need it. It may help
    shorten a crying episode by having another caregiver try to soothe your baby
    during times when you feel overwhelmed and discouraged. Your baby may respond
    better to someone who is “fresh” and relaxed. Plan ahead by scheduling help
    before you need it. Have a list of people to call in case you need help

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.

  • If you are breastfeeding,
    be aware of your diet. The foods you eat may affect your breast milk and
    cause abdominal (belly) pain in your baby, which may extend a crying episode.
  • Feed your baby appropriately. Very young babies may be hungry 1
    to 2 hours after a feeding. Offer food on demand. But to avoid
    overfeeding, be sure to watch for when your
    baby is full.
  • Help prevent
    abdominal gas in your baby. Gas can cause pain,
    leading to extended crying.
  • Practice good hygiene to avoid
    illness. A sick baby usually has more frequent and intense crying episodes. To
    help prevent illness as much as possible, use good hygiene, such as
    washing hands frequently, including your baby’s. Ask
    visitors to do the same. Avoid being around large crowds during a baby’s first
    weeks, especially around people who smoke. Breathing in
    secondhand smoke can increase a baby’s risk for
    respiratory problems,
    ear infections, and


After a colic episode begins, comforting
measures may help.

  • Respond to the crying quickly and
    appropriately. Quickly assess whether a cry likely indicates “I’m hungry” or “I
    need to be changed,” and so on, and act accordingly. Doing so may prevent your
    baby from getting so upset that he or she cannot be consoled. For more
    information on figuring out what your crying baby needs, see the topic
    Crying, Age 3 and Younger.
  • Burp your baby, especially if you suspect abdominal gas started the crying
  • Reduce the activity around your baby. Overstimulation from
    noise, lights, and too much attention can trigger a crying episode. Move your
    baby to a quiet and calm environment.
  • Try
    infant massage. Some parents use infant massage to try
    and relieve colic.
  • Soothe your baby by helping him or her to be more
    comfortable. Don’t worry that you may be spoiling your baby by giving frequent
    and loving attention.

If you find that you are losing patience or are
afraid that you may hurt your baby, act immediately.

  • Place your baby in a crib to cry while you go
    into another room and calm yourself.
  • Ask someone to take over for
    you. If nobody else is home, call a friend who can help you calm down. If you
    are afraid you cannot control yourself and cannot get other help, call

Call your doctor if you frequently feel overwhelmed or
are unable to get adequate support.

Other measures

Do not use
unproven or dangerous treatments for colic.
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:

  • Let your baby stay in the crib and cry
    until he or she is exhausted.
  • Stop breastfeeding your baby. This
    will not cure colic.
  • Give your baby aspirin or aspirin products, because
    of the risk for
    Reye syndrome.
  • Give your baby alcohol
    (even a pacifier dipped in brandy or other alcoholic
  • Shake or spank your baby for crying. Serious or even
    fatal brain injuries may result (shaken baby syndrome).
  • Give your baby
    medicine unless it is recommended or prescribed by
    your doctor.

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.

When to Call a Doctor

Call 911 or other emergency services immediately if:

Call your doctor immediately if your

  • Cries in a peculiar manner or for a very
    unusual length of time.
  • Has not been diagnosed with colic but cries
    excessively and also has symptoms such as vomiting, diarrhea, fever, or blood
    or mucus in the stool.

Call your doctor and schedule an appointment if:

  • Your baby is not gaining
  • Your baby has no symptoms other than crying, but you want
    to check for health problems that may be related.
  • Your baby seems to be acting odd, and you can’t
    identify exactly what concerns you.
  • You have tried
    comfort measures repeatedly and have not been able to
    console your baby.

Also, think about your own health and well-being. Call your
doctor if you:

  • Frequently feel
    anxious or think you may be
  • Feel that you are not able to
    nurture or emotionally connect with your baby.

Who to see

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.

Routine Checkups

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:

  • Will take a
    medical history.
  • Will perform a
    physical exam of your baby.
  • Will ask if
    your baby has other symptoms besides crying.
  • May ask you to keep a
    diary of your baby’s activities.
  • May ask
    you to show how you feed and burp the baby.
  • May ask how your
    baby’s crying affects you.

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.
