Unsettled crying baby

Also called: Infant colic; excessive infant crying

Exercise strongly helps Massage

A baby who cries for hours, often in the evening, with nothing to find. The cause is poorly understood and the crying is real - and the bigger problem, in practice, is the effect on exhausted parents.

How common: Around 20% of infants; peaks at 6 weeks and resolves by 3-4 months

What it is

Infant colic is conventionally defined as crying for more than three hours a day, more than three days a week, in an otherwise healthy, well-fed baby. It typically starts around two weeks, peaks around six weeks and resolves by three to four months.

Nobody knows exactly what causes it, and the honest position is that several things probably contribute in different babies: immature gut motility, feeding factors, and simple variation in infant temperament and crying. What is not in doubt is the effect on parents - exhaustion, guilt, low mood and, in the worst cases, the risk of shaking a baby out of desperation.

What it feels like

Prolonged, intense crying that is hard to console, often in the late afternoon and evening
Drawing the legs up, clenching the fists and going red
Feeding and settling normally at other times of day
Parents exhausted, tearful and feeling they are failing
Resolving on its own by three to four months, which is little comfort at six weeks

What causes it

Most people have more than one of these at once, and they feed each other. Read the list looking for the two or three that sound like your week rather than for the one true answer — the ones that describe you are the ones worth acting on.

Immature gut motility: The gut is still developing coordinated movement in the early months. Gas and discomfort from that immaturity are a plausible contributor, though the evidence is not conclusive.
Normal variation in crying: All babies cry more in the first three months, peaking around six weeks. Colic may partly be the upper end of a normal distribution rather than a distinct condition.
Feeding factors: Fast letdown, air swallowing, overfeeding and, in a minority, cow's milk protein allergy all contribute in some babies. A trial of maternal dairy exclusion helps a small subset.
Infant temperament: Some babies are simply harder to settle and more reactive to stimulation. That is not caused by anything the parents did.
Gut microbiome differences: Differences in gut bacteria have been demonstrated, and specific probiotics have modest evidence in breastfed babies - one of the few interventions with any trial support.
Overstimulation and tiredness: Evening clustering fits an overtired, overstimulated baby who cannot settle. It does not explain everything and it explains some of the timing.
Reflux - less often than assumed: Reflux is commonly blamed and acid-suppressing medication is commonly prescribed, and trials show little benefit for crying alone. It is worth knowing before accepting a prescription.
Parental stress: A genuine two-way relationship: an unsettled baby raises parental stress, and a stressed household can make settling harder. Naming that is not blame - it is a reason to get support.
Things that need excluding: Not colic: a baby who is unwell, feverish, feeding poorly, vomiting, has blood in the stool, is not gaining weight, or whose cry has changed in character needs medical assessment rather than reassurance.

Who tends to get it

All babies in the first three months, in whom crying peaks around six weeks
First-time parents, who have less context for what is normal
Families with limited support, in whom the impact is greatest
Parents with existing anxiety or low mood
Babies with cow's milk protein allergy, which is a small but real subgroup

What makes it worse, and what settles it

Makes it worse

Parental exhaustion, which reduces the capacity to cope with the next episode
Isolation and having nobody to hand the baby to
Overstimulation in the evening
Repeated unnecessary medication trials, which delay acceptance and add stress
Feeling it is your fault, which it is not

Settles it

Motion and rhythm - walking, rocking, a sling, a pram, a car - which soothe more reliably than anything
Gentle abdominal and back massage, which has modest evidence and is at least soothing for both of you
Putting the baby down safely and stepping away for a few minutes when you are at the end of your rope
Sharing the load - handing over to someone else, even briefly
Getting support for yourself, since parental wellbeing is the outcome that matters most here

What actually helps

The short version: Poorly understood - immature gut motility, feeding factors and infant temperament all contribute. Whatever the cause, the crying is real and the effect on parents is the bigger problem

Strength work: Not applicable at this age

Stretching: Gentle leg-cycling and knees-to-tummy movements

Massage: Infant abdominal massage in a clockwise direction following the colon, plus back and leg stroking, 10-15 minutes once or twice a day using a plain oil

Also worth doing: Holding and motion; parent rest and support matters as much as anything done to the baby

What the evidence says: Infant massage reduces crying time in several RCTs, with an effect roughly comparable to the other things parents are offered. It also reliably reduces parental stress, which may matter more. Genuinely a massage-primary entry - one of very few on this list.

No ready-made routine for this one yet

249 of the 267 problems here have a routine already built, and this is not one of them — usually because the work that helps is covered by a general routine rather than needing its own. What actually helps above names the muscles and the work involved, which is enough to put it together yourself.

Get it checked if…

Fever, vomiting, blood in the stool, poor feeding, or a baby who is floppy or hard to rouse is NOT colic - urgent pediatric assessment. Crying that starts after 4 months or that suddenly changes in character also needs review

And whatever the body part: chest pain or unusual breathlessness on exertion; a fever alongside the pain; unexplained weight loss; pain that is constant and unrelated to how you move; new numbness, weakness or loss of bladder or bowel control; or one calf that is swollen, warm and painful. Any of those, stop and get assessed.

How it usually goes

Colic resolves by three to four months in almost every case, which is genuinely reassuring and does not make the middle of it easier. Very few interventions have good evidence; motion, holding and time do most of the work. The most important thing on this page is for parents: never shake a baby, and if you feel you might, put the baby down somewhere safe and walk away for a few minutes. That is the right response, not a failure. Ask for help early rather than late.
