Colic in Infants: Causes, Symptoms, Diagnosis, and Management
Understanding colic: a comprehensive guide for parents on recognizing, managing, and navigating infant colic.
What Is Colic?
Colic is a common condition affecting infants, characterized by significant and prolonged periods of crying or fussiness in an otherwise healthy baby. The episodes often seem unprovoked and can cause distress for parents and caregivers seeking answers or solutions. While colic is not a disease and typically resolves on its own, understanding its signs, potential causes, and approaches to soothing your baby can ease the experience for both your child and your family.
Who Gets Colic?
Colic most commonly affects babies during the first few months of life. It tends to begin around 2 to 3 weeks of age, peaks at about 6 weeks, and usually resolves by 3 to 4 months of age. Colic occurs in both breastfed and formula-fed infants with no predilection for gender, race, or socioeconomic status. While any infant can develop colic, the condition is defined not by who gets it, but rather by its symptoms and their persistence.
Symptoms of Colic
Colic in babies is primarily identified by intense, frequent crying spells that follow a predictable pattern, often in the late afternoon or evening. The crying episodes typically:
- Start and end suddenly, with no obvious cause (not due to hunger or a dirty diaper).
- Last for at least three hours a day, three or more days a week, for at least three weeks.
- Are intense, may sound high-pitched, and can be difficult to soothe.
Associated physical signs during these episodes may include:
- Clenched fists
- Stiffened arms and legs
- Arched back
- Flushed or reddened face
- Burping and passing gas
- Tight or bloated belly
Crying may be accompanied by signs of gastrointestinal discomfort, such as increased gas or apparent belly pain, but colic itself does not cause physical harm or indicate serious medical issues.
Possible Causes of Colic
The exact cause of colic remains unknown. Experts believe a combination of factors may contribute, including:
- Digestive system immaturity: Infant digestive tracts are still developing and may struggle to pass gas or digest certain proteins or sugars.
- Infant temperament and adjustment: Some infants are more sensitive to stimulation or have more difficulty establishing routines and self-soothing behaviors.
- Feeding issues: Overfeeding, underfeeding, or swallowing air during feeding can result in discomfort, gas, or bloating.
- Allergies or sensitivities: In rare cases, sensitivity to cow’s milk protein, lactose, or other formula or dietary components may play a role.
- Family stress: Babies may react to the emotional climate in the household, though colic is not caused by parenting style or mental health.
While many myths surround colic, it is important to recognize that it is a common and typically harmless phase of infancy that is not the fault of the baby or the parents.
How Is Colic Diagnosed?
There is no specific test to diagnose colic. The diagnosis is largely based on your baby’s medical history and a physical examination by a healthcare provider. The following steps may be taken:
- Detailed discussion of the crying episodes, feeding patterns, sleeping habits, and associated behaviors.
- Physical examination to assess the baby’s overall health, including growth (weight, length, head circumference) and vital signs.
- Evaluation for possible signs of infection, gastrointestinal problems, allergies, or other illnesses that could explain persistent crying.
- Review of the baby’s skin, eyes, ears, mouth, limbs, and genitals to rule out other sources of pain or distress.

If the baby’s growth and development are normal and no other cause is found, colic is the likely diagnosis. In some cases, healthcare providers may order tests if symptoms suggest another underlying condition.
Managing Colic: Tips for Parents and Caregivers
There is no single solution to colic, but many strategies can help soothe your baby and support your own well-being during this challenging period. It may take trial and error to find out what works best for your child.
General Soothing Techniques
- Ensure your baby is not hungry and avoid overfeeding.
- If bottle-feeding, keep your baby upright and burp frequently during and after meals to reduce swallowed air.
- If breastfeeding, consider whether your diet or any medications could be affecting your baby—consult your pediatrician.
- Change your baby’s body position frequently and gently massage the back and tummy.
- Swaddle your baby in a soft blanket to create a sense of security.
- Offer a pacifier.
- Provide soothing white noise (such as a fan or soft music) or use recordings of a heartbeat.
- Take your baby on a walk in a stroller or for a ride in the car.
- Try a rocking swing or vibrating seat.
- Soothe your baby with soft talking or singing.
- Give your baby a warm bath if they find it calming.
- Hold your baby against your bare chest (skin-to-skin contact).
Feeding Adjustments
- Feed smaller amounts more frequently to decrease the chance of overfeeding or gas buildup.
- For bottle-fed babies, using a curved, anti-colic bottle may help reduce the amount of air swallowed.
- If symptoms are persistent, consult your pediatrician about changing to a hypoallergenic formula or making dietary adjustments if breastfeeding; some babies may benefit from maternal avoidance of dairy, eggs, soy, or wheat.
Massage Therapy
Research suggests that gentle massage can be more effective than simply rocking in reducing the frequency and intensity of colic episodes. Benefits of massage include:
- Soothing physical discomfort
- Enhancing bonding and trust between parent and baby
- Promoting relaxation for both caregiver and infant
- Improving parental awareness of a baby’s cues and preferences
To get started, gently massage your baby’s back, tummy, arms, and legs for 10-20 minutes, once in the day and again before bedtime. Always stop if your baby seems uncomfortable.
Alternative and Complementary Remedies
Some parents explore herbal teas, gripe water, or other over-the-counter colic remedies. However, these products are not well regulated and may pose risks, such as:
- Reduced milk intake if used as a substitute for feeding
- Potential for contamination, unlabeled ingredients, or inconsistent dosing
- Possible side effects or interactions
Always consult your baby’s healthcare provider before using herbal or alternative remedies. There is limited and mixed evidence for their effectiveness, and the risks may outweigh potential benefits.
Sleeping Positions and Safety
Never place your child to sleep on their stomach or side. The safest sleep position for infants is flat on their backs to reduce the risk of sudden infant death syndrome (SIDS). For soothing, you can lay your baby tummy-down across your lap and gently rub their back, but always return them to their back if they fall asleep.
Dealing with Stress as a Parent
Caring for a colicky baby can be exhausting and overwhelming. It is important to acknowledge your feelings and seek support when needed:
- Take breaks by asking for help from family or friends.
- Set your baby in a safe crib and step away for a few minutes if you feel frustrated.
- Connect with other parents or a support group for reassurance and advice.
- Take care of your own health—rest, hydration, nutrition, and emotional support are vital.
Never shake a baby. If you struggle to manage your emotions, reach out to your healthcare provider for guidance and resources.
When Should You Call Your Doctor?
While most colicky babies are healthy otherwise, seek medical attention if your infant experiences any of the following signs:
- Vomiting, especially if green or bloody
- Persistent diarrhea
- Blood in stool
- Fever (rectal temperature 100.4°F or higher in infants under 3 months)
- Refusal to feed or poor weight gain
- Unusual lethargy or weakness
- Seizures or abnormal movements
- Sudden change in how your baby cries (very weak, high-pitched, or piercing)
If you have concerns about your baby’s crying, feeding, or general health, do not hesitate to contact your pediatrician. They can help distinguish colic from conditions that may require medical attention.
Frequently Asked Questions (FAQs) About Colic
Q: Is colic harmful to my baby?
A: Colic itself is not dangerous and does not cause permanent harm. However, it can be distressing for both babies and parents. Persistent crying does not increase the risk of health problems or developmental delays if the baby is otherwise healthy and gaining weight.
Q: How long does colic last?
A: Most cases of colic resolve on their own by 3 to 4 months of age, although some babies may experience symptoms up to 6 months. If your baby’s excessive crying continues beyond this age, speak with your healthcare provider.
Q: Does my baby’s diet cause colic?
A: While specific foods or milk proteins can contribute to symptoms in rare cases, most babies do not have dietary allergies causing colic. Discuss any concerns with your pediatrician before making significant changes to feeding routines.
Q: Can medications help with colic?
A: There is no proven medication to treat colic, and most over-the-counter remedies are not supported by strong evidence. Soothing strategies and parent support are the mainstays of management.
Q: Should I be worried about my baby’s crying?
A: It is normal to feel worried or frustrated. If your baby’s crying changes in character, or is associated with other symptoms like fever, vomiting, decreased feeding, or weight loss, contact your healthcare provider for further evaluation.
Key Points to Remember
- Colic is defined by repeated, often intense crying spells in a healthy infant, typically beginning within the first weeks of life.
- Although the cause is unclear, colic resolves naturally in most babies and is not harmful in itself.
- Soothing and calming techniques can help your baby and provide you support during challenging episodes.
- Always practice safe sleep and feeding routines, and consult your pediatrician with any concerns or persistent symptoms.
