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.
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.
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
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
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

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.

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.

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.
