Colic

Updated: 07-06-2011

Definition

If your baby cries about the same time each day and nothing you do seems to offer comfort, your baby may have colic. Colic is often defined as crying more than three hours a day, three days a week for more than three weeks in an otherwise well-fed, healthy baby. What is most important for the diagnosis is sustained crying in an otherwise healthy baby for a regular period of the day lasting for several weeks.

Colic can be distressing for both you and your baby. But take comfort: Colic is relatively short-lived. In a matter of weeks or months, the colic will end, and you'll have weathered one of the first major challenges of parenthood.

Symptoms

Fussing and crying are normal for infants, and a fussy baby doesn't necessarily have colic. In an otherwise healthy, well-fed baby, signs of colic include:

  • Predictable crying episodes. A baby who has colic often cries about the same time every day, usually in the late afternoon or evening. Colic episodes may last from a few minutes to three hours or more on any given day. The crying usually begins suddenly and for no clear reason. Your baby may have a bowel movement or pass gas near the end of the colic episode.
  • Intense or inconsolable crying. Colic crying is intense and often high pitched. Your baby's face may flush, and he or she is extremely difficult — if not impossible — to comfort.
  • Posture changes. Curled up legs, clenched fists and tensed abdominal muscles are common during colic episodes.

Colic affects as many as 25 percent of babies. Colic usually starts a few weeks after birth and often improves by age 3 months. By ages 4 to 5 months, the majority of babies with colic have improved.

When to see a doctor
Seek immediate medical attention if your baby's crying could be the result of a fall or injury.

Contact your baby's doctor if you're concerned about your baby's crying, especially if you notice changes in your baby's eating, sleeping or behavior. You can help your baby's doctor by tracking in a diary when your baby cries and for how long. Also record your baby's sleeping and eating patterns.

Causes

The cause of colic is unknown. Researchers have explored a number of possibilities, including allergies, lactose intolerance, an immature digestive system, maternal anxiety, and differences in the way a baby is fed or comforted. Yet it's still unclear why some babies have colic and others don't.

Risk factors

Infants of mothers who smoke during pregnancy or after delivery have a greater risk of developing colic.

Many other theories about what makes a child more susceptible to colic have been proposed, but none have been proved. Colic doesn't occur more often among firstborns or formula-fed babies. A breast-feeding mother's diet isn't likely to trigger colic. Girls and boys — no matter what their birth order or how they're fed — experience colic in similar numbers.

Complications

Although colic often takes a toll on the entire family, it doesn't appear to have any lasting medical consequences. Babies who have colic grow and develop normally.

Preparing for your appointment

When you take your baby to his or her pediatrician or family doctor, it's a good idea to be well prepared for your appointment. Here's some information to help you get ready for your appointment, and what to expect from your doctor.

What you can do

  • Track your baby's crying episodes, including when and how often they occur, how long they last, and any observations you've made about your baby's behavior before, during and after the episodes.
  • Write down how you've tried to soothe your baby and the results.
  • Write down questions to ask your doctor.
  • Record your baby's diet and feeding schedule, as well as weight gain or loss.

Preparing a list of questions will help you make the most of your time together. List your questions from most important to least important in case time runs out. For colic, some basic questions to ask your doctor include:

  • Does my baby have colic or is there another reason for the crying episodes?
  • What effects can colic have on my baby's growth and development?
  • What is the best course of action?
  • Are there any brochures or other printed material that I can take home with me? What websites do you recommend visiting?
  • What should my family and I do to cope with the crying?

In addition to the questions that you've prepared to ask your doctor, don't hesitate to ask questions during your appointment.

What to expect from your doctor
Your baby's doctor is likely to ask a number of questions, such as:

  • What other behaviors might your baby display during a crying episode?
  • When does the crying usually occur?
  • How long do crying episodes tend to last?
  • What does your baby's cry sound like?
  • What things do you do to try to soothe your baby?
  • Does your baby have any problems with eating?
  • What do you feed your baby and how often do you feed him or her?
  • How often and how much does your baby spit up?
  • Does your baby ever seem to have trouble breathing during these episodes?
  • How do you cope when your baby is crying?
  • How has your baby's crying affected your family?
  • What do you think might be causing your baby's crying?

Tests and diagnosis

Your baby's doctor will do a physical exam to identify any possible causes for your baby's distress, such as an intestinal obstruction. If your baby is otherwise healthy, he or she may be diagnosed with colic.

Lab tests, X-rays and other diagnostic tests aren't usually needed, but in unclear cases they help to exclude other diagnoses.

Treatments and drugs

Colic improves on its own, often by age 3 months. In the meantime, there are few treatment options. Gas-relief medications, such as simethicone (Gas-X Infant Drops, Infants' Mylicon Gas Relief, others), haven't proved very helpful.

Some research suggests that treatment with probiotics — substances that help maintain the natural balance of "good" bacteria in the digestive tract — can soothe colic. More research is needed, however, to determine the effects of probiotics on colic.

Talk to your baby's doctor before giving your baby any medication to treat colic.

Lifestyle and home remedies

Your baby's doctor may not be able to fix colic or make it go away sooner, but there are many ways you can try to soothe your baby. Consider these suggestions:

  • Feed your baby. If you think your baby may be hungry, try a feeding. Hold your baby as upright as possible, and burp your baby often. Sometimes more frequent — but smaller — feedings are helpful. If you're breast-feeding, it may help to empty one breast completely before switching sides. This will give your baby more hindmilk, which is richer and potentially more satisfying than the foremilk, which is present at the beginning of a feeding.
  • Offer a pacifier. For many babies, sucking is a soothing activity. Even if you're breast-feeding, it's OK to offer a pacifier to help your baby calm down.
  • Hold your baby. Cuddling helps some babies. Others quiet when they're held closely and swaddled in a lightweight blanket. To give your arms a break, try a baby sling, backpack or other type of baby carrier. Don't worry about spoiling your baby by holding him or her too much.
  • Keep your baby in motion. Gently rock your baby in your arms or in an infant swing. Lay your baby tummy down on your knees and then sway your knees slowly. Take a walk with your baby, or buckle your baby in the car seat for a drive. Use a vibrating infant seat or vibrating crib.
  • Sing to your baby. A soft tune might soothe your baby. And even if lullabies don't stop your baby from crying, they can keep you calm and help pass the time while you're waiting for your baby to settle down. Recorded music may help, too.
  • Turn up the background noise. Some babies cry less when they hear steady background noise. When holding or rocking your baby, try making a continuous "shssss" sound. Turn on a kitchen or bathroom exhaust fan, or play a tape or CD of environmental sounds, such as ocean waves, a waterfall or gentle rain. Sometimes the tick of a clock or metronome does the trick.
  • Use gentle heat or touch. Give your baby a warm bath. Softly massage your baby, especially around the tummy.
  • Give your baby some private time. If nothing else seems to work, a brief timeout might help. Put your baby in his or her crib for five to 10 minutes.
  • Mix it up. Experiment to discover what works best for your baby, even if it changes from day to day.
  • Consider dietary changes. If you breast-feed, see if eliminating certain foods from your own diet — such as dairy products, citrus fruits, spicy foods or drinks containing caffeine — has any effect on your baby's crying. If you use a bottle, a new type of bottle or nipple might help.
  • Let someone else take over for a time. It's stressful to listen to your baby cry for long periods, so give yourself a break. Arrange ahead of time for someone you can call to help with the baby so that you can have a few moments of relief.

Alternative medicine

Some parents report soothing their crying infants with alternative remedies. The remedies include:

  • Herbal teas
  • Herbal remedies, such as fennel oil
  • Glucose
  • Massage therapy

Alternative therapies for colic haven't proved to be consistently helpful, however, and some might even be dangerous. Talk to your baby's doctor before trying any alternative therapies for colic.

Coping and support

Caring for an infant who has colic can be exhausting and stressful, even for experienced parents. Remember to take care of yourself, too. These suggestions may help:

  • Take a break. When you've done what you can, ask your spouse or partner or another loved one to take over for a while. Take advantage of baby-sitting offers from friends or neighbors. Even an hour on your own can help refresh you.
  • Express your feelings. It's normal for parents in this situation to feel helpless, depressed or angry. Confide in your spouse, partner or other good listener.
  • Try to stay positive. Don't measure your success as a parent by how much your baby cries. Colic isn't a result of poor parenting.
  • Make healthy lifestyle choices. Eat healthy foods. Make time for exercise, such as a brisk daily walk. If you can, sleep when the baby sleeps — even during the day. Avoid alcohol and other drugs.
  • Remember that it's temporary. Colic episodes often improve by age 3 months.

It's also important to recognize your limits. If your baby's crying is causing you to lose control, put the baby in a safe place — such as a crib — and go to another room to collect yourself. If necessary, contact your doctor, a local crisis intervention service or a mental health help line for additional support. These suggestions apply not only to parents but also to any other person who cares for your child.
