Baby Colic - Causes, Symptoms & Survival Guide 2026


Published - February 22 Last Updated: February 22, 2026

Every evening from 6 p.m. to 11 p.m., my son screamed. Not cried—screamed. Nothing helped. I walked miles bouncing at him, tried every hold, every sound. Some nights, I sobbed with him. At 12 weeks, it stopped as suddenly as it started. Baby Colic is hell. 

If you're in it, you need to hear this: it's not your fault, it will end, and you're going to survive this even though it doesn't feel like it. Here's everything that might help—and what won't.

Colic is one challenging newborn phase—explore our complete newborn health guide for all health and care topics.


Baby Colic


What Is Baby Colic?

Definition (Rule of Threes)

Baby colic is defined by the "rule of threes":

  • Crying for 3 or more hours per day
  • At least 3 days per week
  • For 3 or more weeks
  • In an otherwise healthy baby

This isn't just normal fussiness. It's intense, often inconsolable crying that happens despite your baby being fed, changed, and not sick.

How Common (20-25% of Babies)

Colic affects about 20-25% of babies. It doesn't discriminate. It happens to breastfed and formula-fed babies equally. First babies and fifth babies. Boys and girls. Your parenting didn't cause it.

Not Your Fault

Let's be crystal clear: You did not cause your baby's colic. You're not doing something wrong. You're not a bad parent. Colic happens to babies of amazing parents who are doing everything right.

When Colic Starts and Ends

Starts - Usually 2-3 weeks after birth. 

Peaks - Around 6 weeks (the worst part). 

Improves - By 3 months. 

Ends - Typically by 4 months

Knowing this timeline helps. When you're at week 7 in the thick of it, you typically, urself: "One more month. Just one more month."

Recognizing Baby Colic

Intense, Inconsolable Crying

Colic crying differs from normal crying. It's intense, piercing, and nothing you do makes it stop. You've fed baby, changed baby, held baby, walked baby—and they're still screaming.

Learning to recognize different types of cryingcolic crying has a distinct, intense quality.

Clenched Fists and Tensed Body

During colic episodes, the baby's whole body tenses up. Fists clench tight. Arms and legs pull in. The entire body seems rigid with distress.

Red Face, Arched Back

Baby's face turns bright red from crying. Back arches. It looks like the baby is in serious pain, which is terrifying for parents.

Pulling Legs to Chest

Many colicky babies pull their legs up to their chest repeatedly, which often makes parents think it's gas pain. It might be, but it's not the whole story.

Crying at Predictable Times (Usually Evening)

The "witching hour “for many babies, colic happens concurrently every day, usually in the evening. 5 p.m. to 11 p.m. is a common time. Some parents can set their watch by when crying starts.

Distinguished colic from normal evening cluster feeding patterns—both involve fussiness, but differ in intensity and duration.

Baby Otherwise Healthy

Here's the key: when the baby isn't crying, it's fine. They eat well. They gain weight. They have normal alert periods. They're developing normally. Baby colic doesn't mean anything is mistaken with your baby's health or future.

Colic crying differs from normal sleep resistance; it's more intense and lasts for hours.

Colic vs. Other Issues

Colic vs. Normal Crying

Normal crying: Stops when you address the need (feed, change, hold). Colic - Continues for hours despite meeting all needs

Colic vs. Reflux

Learn to differentiate between colic and reflux symptoms, such as arching, spitting up, and feeding aversion. Reflux babies often:

  • Spit up a lot
  • Refuse to eat
  • Cry during and after feeding
  • Have trouble gaining weight

Colic babies cry intensely but eat well and gain weight normally.

Colic vs. Gas

Understanding gas vs. colic helps target the right interventions—they're related but not the same. Gas causes discomfort. Colic is intense crying that may cause gas (from swallowing air while crying), but gas doesn't cause colic.

Colic vs. Milk Allergy

Milk protein allergy symptoms include:

  • Blood in poop
  • Severe eczema
  • Fussiness ALL day (not just evening)
  • Poor weight gain
  • Vomiting

True colic - intense crying, but the baby is healthy otherwise.

Colic vs. Illness

Know when crying signals illness versus colic—fever, lethargy, poor feeding require evaluation. Illness includes: fever, vomiting, diarrhea, refusing to eat, extreme lethargy, and not waking to feed.

When It's Not "Just Colic"

If the baby has other symptoms beyond crying—fever, poor feeding, blood in stool, not gaining weight—get medical evaluation. Don't assume everything is "just colic."

What Causes Baby Colic? (We Don't Really Know)

Theories

Honestly, we don't know what causes baby colic. Theories include:

Immature digestive system - Maybe the baby's gut is still learning to process food, and this causes discomfort.

Overstimulation/sensory overload - Perhaps some babies get overwhelmed by stimulation during the day and melt down in the evening.

Immature nervous system - A baby's nervous system might not regulate well yet.

Normal developmental phase - This might just be a stage some babies go through.

Combination of factors - Probably multiple things together.

What Doesn't Cause Colic

Not bad parenting - You didn't do this.

Not something you're doing wrong - Even perfect parents have colicky babies.

Not necessarily related to feeding method - Breastfed and formula-fed babies get colic equally.

The Colic Timeline

Typically Starts 2-3 Weeks

Most babies don't have colic from birth. It starts around 2-3 weeks of age.

Peaks Around 6 Weeks

Week 6 is usually the absolute worst. The crying is the longest and most intense. If you're there now, you're in the hardest part.

Improves by 3 Months

Around 3 months, most babies improve significantly. Crying episodes get shorter, less frequent, and less intense.

Resolved by 4 Months (Usually)

By 4 months, most colic is completely gone. Baby is a different baby—happy, content, normal.

Why Knowing Timeline Helps

When you're in hour 3 of screaming at week 7, knowing "this ends in 5 weeks" helps you survive. It gives you a light at the end of the tunnel.

Soothing Techniques That May Help

Nothing "cures" baby colic, but these techniques help some babies sometimes -

The 5 S's (Swaddle, Side, Shush, Swing, Suck)

Dr. Harvey Karp's method helps many babies:

  • Swaddle - Wrap baby snugly
  • Side/stomach position - Hold baby on side or stomach (not for sleeping)
  • Shush - Loud white noise
  • Swing - Rhythmic motion
  • Suck - Pacifier or nursing

White Noise

Loud white noise—like a vacuum cleaner, hair dryer, or white noise machine on high. Needs to be LOUD to work.

Motion (Rocking, Bouncing, Walking, Car Rides)

Constant motion helps some babies. Rock vigorously, bounce on an exercise ball, walk around the house, drive around the block. Some parents walk miles every night.

Colic Hold/Gas Hold

Hold baby face down along your forearm, head in your hand, legs straddling your elbow. This position can be comforting.

Warm Bath

A warm bath calms some colicky babies. Even if it only helps for 10 minutes, that's 10 minutes of peace.

Pacifiers

Some colicky babies need constant sucking. A pacifier can help.

Skin-to-skin contact

Hold the baby against your bare chest. The warmth, heartbeat, and closeness comfort some babies.

Change of Environment

Sometimes going outside, changing rooms, or changing who's holding the baby helps reset things.

Baby Wearing

Wearing a baby in a carrier while you move around can provide constant motion and closeness.

What rarely works

Gas Drops (Limited Evidence)

Gas drops (simethicone) have limited scientific evidence. They don't cure colic. They might help a tiny bit with gas discomfort, but don't expect miracles.

Gripe Water (Not FDA Regulated, Inconsistent)

Gripe water isn't FDA-regulated. Ingredients vary by brand. Some contain alcohol (avoid those). Most parents report it doesn't help colic, though some swear by it.

Dietary Changes (Unless True Allergy)

For most colicky babies, eliminating foods from the breastfeeding mom's diet doesn't help. Only try this if the doctor suspects milk protein allergy (with other symptoms like blood in stool).

Special Formulas (Usually)

Switching formulas rarely helps true colic. It might help if the baby has reflux or a milk allergy, but that's not the same as colic.

Chiropractic/Craniosacral (No Evidence)

There's no scientific evidence that chiropractic adjustments or craniosacral therapy help colic. Save your money.

Medical Evaluation

When to Call a Doctor

Get an evaluation if:

  • Crying started suddenly and is severe
  • Baby has a fever
  • Baby won't eat or is losing weight
  • Vomiting, diarrhea, or blood in stool
  • Baby seems to be in pain (not just crying)
  • You need reassurance that it's "just" colic

Ruling Out Medical Causes

Your pediatrician will check for -

  • Reflux
  • Milk protein allergy
  • Ear infection
  • Intestinal issues
  • Other causes of pain

What a Pediatrician Will Check

The doctor will examine the baby thoroughly, ask about symptoms, check weight gain, and may order tests if concerned about specific issues.

When Testing Is Needed

If the baby has symptoms beyond crying—poor weight gain, blood in stool, vomiting—testing may be needed. Pure colic doesn't require tests.

Feeding Modifications to Try

Smaller, More Frequent Feeds

Instead of large feeds, try smaller amounts more often. This may reduce digestive discomfort.

Burping Frequently

Burping babies often during feeding reduces swallowed air.

Paced Bottle Feeding

If bottle-feeding, use the paste feeding technique to slow down milk flow and reduce air swallowing.

Eliminating Dairy (Breastfeeding Moms—If suggested)

Only try this if your doctor suspects milk protein allergies. Don't randomly eliminate foods—it rarely helps pure colic.

Hypoallergenic Formula Trial (If recommended)

If the doctor suspects a milk protein issue, they may suggest trying a hypoallergenic formula for 1-2 weeks.

What NOT to Change Without Guidance

Don't randomly switch formulas, eliminate multiple foods, or make major changes without a doctor's input. This rarely helps and adds stress.

Surviving Colic - Parent Mental Health

Normal to Feel Overwhelmed, Angry, Desperate

Hours of inconsolable crying trigger intense emotions. Frustration. Anger. Desperation. Helplessness. Guilt. These feelings are completely normal. Experiencing those emotions doesn’t make you an unfit parent.

Colic mushrooms parental stress—protecting your mental health is critical during this phase.

Taking Breaks (It's Okay to Put Baby Down Safely and Walk Away)

When you're at your breaking point:

  • Put the baby in the crib (safe place)
  • Walk into another room
  • Take 5-10 minutes to breathe
  • Baby will be fine crying in the crib

This is not abandonment. This is survival. This is smart parenting.

Tag-teaming with Partner

If you have a partner, take shifts. One person handles 6-8 p.m., the other handles 8-10 p.m. Trade off nights. Don't try to suffer through it together every night.

Accepting Help

If someone offers to hold the baby for an hour, say YES. Take a shower. Take a nap. Leave the house. You need breaks.

Recognizing Postpartum Depression/Anxiety

Prolonged, inconsolable crying can signal postpartum depression—stay alert to warning signs and seek support. Signs include:

  • Feeling hopeless
  • Not bonding with the baby
  • Thoughts of harming yourself or your baby
  • Extreme anxiety
  • Can't sleep even when the baby sleeps

Get help immediately if you're experiencing these.

Never Shake Baby

NEVER shake your baby. Shaking can cause brain damage or death. If you feel that urge, put the baby down safely and walk away immediately. Call someone for help.

Resources and Support

Colic Support Groups

Online support groups for parents of colicky babies help you feel less alone. Hearing "me too" from other parents helps.

Partner Communication

Talk to your partner about how you're feeling. Don't suffer in silence. Work together to survive this phase.

Professional Help for Mental Health

If you're struggling, talk to your doctor. Therapy helps. Medication helps. Getting support is not a weakness; it's a strength.

Temporary Childcare/Relief

Hire a mother's helper for a few hours. Ask family to help. Use postpartum doula services. Get breaks however you can.

Light at the End of the Tunnel

This Phase Ends

Baby Colic Ends. Usually by 4 months, sometimes by 3 months. It feels endless, but it's not. You will get through this.

No Long-Term Effects on Baby

Colic doesn't damage your baby. It doesn't mean the baby will have behavioural problems. It doesn't affect development. When colic ends, the baby is perfectly normal and healthy.

You're Doing Your Best

You're surviving one of the hardest phases of parenting. The fact that you're reading this, trying to help your baby, shows you're a good parent.

It Gets Better (And It Will)

One day soon, your baby will smile. Will laughed. Will be content. The screaming will be a memory. You'll survive this. I promise.

Frequently Asked Questions

Q: How do I know if it's colic or something medical?

A: Colic = intense crying, but baby otherwise healthy (eating, gaining weight, alert periods, normal diapers). Medical issues usually include other symptoms: fever, vomiting, diarrhea, blood in stool, poor weight gain, and lethargy. When in doubt, get evaluated.

Q: Will changing my diet help if I'm breastfeeding?

A: For most colicky babies, no. Only try an elimination diet if the doctor suspects milk protein allergy (symptoms: blood in stool, eczema, severe fussiness ALL day). Random food eliminations rarely help true colic.

Q: Is colic caused by gas?

A: Not exactly. Babies with colic may swallow air from crying, causing gas. But gas doesn't cause the colic—the crying comes first. Gas drops don't cure colic, though they may help some babies feel slightly more comfortable.

Q: When will it end?

A: Most colic improves significantly by 3 months and is completely resolved by 4 months. Peak is usually around 6 weeks. Mark your calendar—knowing there's an endpoint helps mentally.

Q: Is it okay that I sometimes feel angry at my baby?

A: Yes. Hours of inconsolable crying trigger intense emotions, frustration, anger, desperation, and helplessness. These feelings are normal. What matters is that you never act on them (never shake a baby) and you get support for your mental health.
