Baby Colic (Infantile Colic)
Baby colic, also known as infantile colic, refers to frequent and prolonged episodes of crying in an otherwise healthy and well-fed baby without an identifiable medical cause. The crying can be intense and difficult to soothe, and it often occurs at approximately the same time of day, particularly during the late afternoon or evening. Colic is common during the first few months of life. It usually begins when a baby is a few weeks old, tends to become more noticeable around 4–6 weeks of age, and gradually improves by 3–4 months of age. Although colic can be stressful for parents and caregivers, it generally does not cause long-term health problems. However, excessive crying can sometimes be a sign of another medical condition, so persistent, unusual, or severe crying should be discussed with a pediatrician.
Traditionally, colic has been described using the “three-rule”: crying for more than 3 hours a day, more than 3 days a week, for at least 3 weeks, in an otherwise healthy infant. Today, doctors recognize that infantile colic can occur in a broader range of patterns and do not rely solely on this definition. The important features are recurrent episodes of excessive crying or fussiness in an infant who otherwise appears healthy and is developing normally. During an episode, a baby may cry intensely, appear uncomfortable, and be difficult to calm. The baby may stop crying suddenly and then become comfortable again.
Common signs and symptoms include:
- Crying loudly and intensely, sometimes as if the baby is in pain
- Crying that is difficult to soothe
- Sudden episodes of crying that may start and stop unexpectedly
- Crying that frequently occurs in the late afternoon or evening
- Episodes that may last for several hours
- Clenched fists during crying
- Drawing the legs up toward the abdomen
- Stiffening or stretching the legs
- A tense-looking or bloated abdomen
- Red or flushed face while crying
- Passing gas or increased burping
- Difficulty settling or falling asleep during an episode
A baby with colic generally continues to feed, gain weight, and behave normally between episodes.
The exact cause of infantile colic is not known. It is probably not caused by a single factor. Several physical, developmental, feeding-related, and environmental factors may contribute to excessive crying. Possible contributing factors include:
A young baby’s digestive system is still developing. Gas, intestinal movement, and difficulty coordinating digestion may contribute to discomfort in some babies.
A baby may become unsettled because of hunger, feeding too frequently, feeding too quickly, or taking in excess air while feeding.
Babies can swallow air while breastfeeding or bottle-feeding. If the baby is not burped adequately, swallowed air may contribute to abdominal discomfort.
Young babies may become overwhelmed by excessive light, noise, movement, handling, or other environmental stimulation. Some babies are more sensitive than others.
A small number of babies may have an intolerance or allergy to proteins in cow’s milk. In breastfed babies, proteins from the mother’s diet can pass into breast milk. However, cow’s-milk protein allergy is not the usual cause of colic. It should be considered particularly when excessive crying occurs together with symptoms such as blood or mucus in the stool, vomiting, diarrhea, eczema, poor feeding, or poor weight gain.
Some babies have reflux, in which stomach contents flow back into the food pipe. Mild reflux is common in infants, but significant reflux disease may cause feeding difficulties, frequent vomiting, or discomfort.
Crying naturally increases during the first few months of life. The baby’s developing nervous system may have difficulty regulating sleep, feeding, stimulation, and emotions.
Stress, changes in routine, excessive stimulation, or difficulty establishing feeding and sleeping routines may sometimes make an infant more difficult to settle. This does not mean that parents or caregivers have caused the colic.
Not every crying baby has colic. Certain medical conditions can cause prolonged or sudden crying and need to be ruled out by a pediatrician when appropriate. These may include:
- Ear infection
- Urinary tract infection
- Constipation
- Gastroesophageal reflux disease
- Cow’s-milk protein allergy
- Incarcerated or painful hernia, including an inguinal hernia
- Hair or thread wrapped tightly around a finger or toe
- Eye irritation or injury
- Injury or trauma
- Fever or other infection
- Rare neurological or other serious medical conditions
For this reason, a baby with a sudden change in crying pattern, persistent unexplained crying, or other concerning symptoms should be evaluated by a doctor.
Colic can occur in babies regardless of sex, feeding method, or family background. Some factors have been associated with increased crying, although they do not necessarily mean that a baby will develop colic. Possible factors include:
- Premature birth
- Exposure to cigarette smoke during pregnancy or after birth
- Difficulties with feeding
- Increased sensitivity to environmental stimulation
- Family stress
Colic can also occur in babies who have no identifiable risk factors.
There is no specific laboratory test or imaging study that confirms colic. A pediatrician usually diagnoses colic based on the baby’s:
- Age
- Crying pattern
- Feeding history
- Sleeping pattern
- Growth and development
- Physical examination
- Other symptoms, if present
The doctor may ask parents:
- When the crying usually occurs
- How long each episode lasts
- How often the baby cries
- Whether the baby feeds normally
- Whether the baby is gaining weight
- Whether there is vomiting, diarrhea, constipation, fever, or blood in the stool
- Whether the baby’s abdomen appears swollen
- Whether anything makes the crying better or worse
If the examination and history are reassuring, no additional tests may be necessary.
There is no single treatment that cures colic in every baby. Most babies improve naturally as they mature. Treatment generally focuses on comforting the baby, identifying possible triggers, supporting feeding, and reassuring parents.
Try holding the baby close, gently rocking, carrying, or walking with the baby. Some babies respond well to skin-to-skin contact.
A quiet, calm environment may help. Dim lighting and reduced noise can be useful when the baby appears overstimulated.
Slow rocking, walking, or gently pushing the baby in a stroller may help some infants settle.
Burping during and after feeding may reduce swallowed air. However, not every baby needs to burp after every feed.
For bottle-fed babies, ensure that the nipple flow is appropriate and that the baby is not swallowing excessive air. Breastfeeding mothers should seek professional advice if there are concerns about positioning, attachment, or milk transfer.
A predictable pattern for feeding, sleep, and soothing may help some babies settle more easily.
Some babies may respond to soft, continuous sounds such as a fan or white-noise machine. The sound should be kept at a safe volume and placed away from the baby’s head.
A comfortably warm bath may help some babies relax. The baby should never be left unattended around water.
If a doctor suspects cow’s-milk protein allergy or another feeding-related problem, a supervised dietary change may be recommended. Parents should not make major dietary changes or switch formulas repeatedly without medical advice, particularly because unnecessary restrictions can affect maternal nutrition or the baby’s nutritional intake.
Parents often look for medicines, herbal remedies, or supplements to treat colic. However, many products marketed for colic have limited or inconsistent evidence. Do not give a baby medicines, herbal preparations, gripe water, or supplements without discussing them with a pediatrician. Some studies suggest that specific probiotic preparations may help certain breastfed babies, but the evidence is not consistent for all infants, and probiotics should not be considered a universal treatment for colic.
There is no guaranteed way to prevent colic because its exact cause is unknown. However, parents can try to reduce factors that may contribute to excessive crying:
- Feed the baby according to hunger cues
- Avoid overfeeding
- Ensure proper breastfeeding or bottle-feeding technique
- Burp the baby when appropriate
- Keep the baby upright for a short period after feeding when advised
- Avoid excessive noise and stimulation
- Establish a calm bedtime routine
- Provide plenty of comforting physical contact
- Avoid exposing the baby to cigarette smoke
Consult a pediatrician if:
- The baby’s crying is persistent or unusually severe
- The baby is difficult to feed
- The baby is not gaining weight normally
- The baby frequently vomits
- The baby has diarrhea or persistent constipation
- There is blood in the stool
- The baby’s abdomen is persistently swollen
- The baby appears to be in significant pain
- The baby’s crying pattern suddenly changes
- You are worried that something is wrong
A pediatrician can determine whether the crying is consistent with colic or whether another condition needs to be investigated.
Seek urgent medical attention if a crying baby has any of the following:
- Fever, especially in a very young infant
- Difficulty breathing
- Blue, gray, or unusually pale skin
- Extreme sleepiness or difficulty waking
- Seizures
- Repeated or forceful vomiting, particularly green vomit
- Blood in vomit or stool
- A swollen or very tender abdomen
- Refusal to feed
- Significantly fewer wet diapers
- A weak, high-pitched, or unusual cry
- Sudden inconsolable crying following an injury
- A swollen, painful groin or scrotum
- A baby who appears seriously unwell
When in doubt, it is safer to have a young infant assessed by a healthcare professional.
Colic can be exhausting and emotionally challenging for parents and caregivers. Continuous crying can cause frustration, anxiety, and sleep deprivation. Remember that your baby’s crying is not necessarily a reflection of your parenting. If you feel overwhelmed:
- Place the baby safely on their back in an empty crib and take a short break.
- Ask a trusted family member or caregiver to help.
- Try to rest whenever possible.
- Speak with your pediatrician if you are struggling to cope.
Never shake, hit, or roughly handle a crying baby. Shaking an infant can cause severe brain injury or death.
The outlook for babies with colic is generally very good. Colic usually begins during the first few weeks of life, becomes more noticeable during the first couple of months, and gradually improves as the baby’s nervous and digestive systems mature. Most babies outgrow colic by around 3–4 months of age, although the exact duration varies from one baby to another. Colic generally does not interfere with a baby’s long-term growth or development when the baby is otherwise healthy.
Pediatrician- A pediatrician can evaluate excessive crying, assess the baby’s feeding and growth, rule out medical causes, and provide appropriate guidance for managing colic.
Baby colic is a pattern of frequent, prolonged, and difficult-to-soothe crying in an otherwise healthy infant. It commonly occurs during the first few months of life.
Colic commonly begins when a baby is a few weeks old and often becomes more noticeable around 4–6 weeks of age.
Most babies gradually improve by around 3–4 months of age. Some may experience symptoms for longer.
Gas may contribute to discomfort in some babies, but colic is not known to have a single cause. Swallowed air and digestive immaturity may contribute to crying in some infants.
Colic itself is generally not dangerous and usually resolves as the baby matures. However, some medical conditions can cause excessive crying, so warning signs should not be ignored.
Do not repeatedly change formula without medical advice. If a pediatrician suspects cow’s-milk protein allergy or another feeding problem, they may recommend a specific formula or supervised dietary trial.
Breastfeeding does not guarantee that a baby will not develop colic. Colic can occur in both breastfed and formula-fed babies.
Gripe water and other over-the-counter or herbal preparations are not universally proven to treat colic. Consult your pediatrician before giving any such product to an infant.
If you are becoming overwhelmed, it is safer to place your baby on their back in a safe crib and step away briefly than to continue trying to soothe the baby while extremely frustrated. Never shake or roughly handle an infant.
Seek medical advice if crying is persistent, suddenly different, associated with poor feeding, fever, vomiting, blood in the stool, breathing difficulty, unusual sleepiness, injury, or any other concerning symptom.
