Every baby cries, and in the first few months, it can feel like a lot. Crying that peaks in the evenings, resists soothing, and leaves you wondering if something is wrong is genuinely one of the hardest parts of early parenting. This article covers what colic actually is, what helps, what doesn't, and how to tell ordinary (if exhausting) crying apart from crying that needs a doctor's attention.
What "normal" crying looks like
Crying is a normal, expected way for a young baby to communicate, and it follows a fairly predictable pattern across infancy. Crying typically increases over the first few weeks, peaks at around 6 to 8 weeks of age (averaging roughly 2 to 3 hours across a 24-hour day at its peak), is often worse in the late afternoon or evening, and then gradually settles by around 3 to 4 months. This pattern holds broadly true whether or not a baby ends up being labelled as having colic.
What colic actually means
"Colic" doesn't have one single, universally agreed clinical definition, but the most commonly used reference point is the classic "rule of three": crying for more than 3 hours a day, on more than 3 days a week, for more than 3 weeks, in a baby who is otherwise healthy, feeding well, and growing normally. Colic crying is also often described as sudden in onset, harder to soothe than ordinary fussiness, and sometimes accompanied by the baby drawing their legs up as if in discomfort.
It's worth being clear about what this means in practice: colic is a description of a crying pattern, not a diagnosis you can make from a single bad evening, and it's a conclusion reached after other explanations have been reasonably considered, not a default label for any baby who cries a lot.
Not every crying baby has colic
Before settling on "it's just colic," it's worth running through the ordinary, easily-fixed reasons a baby cries: hunger, a wet or soiled diaper, being too hot or too cold, wanting to be held, tiredness, or simple overstimulation. Beyond these, a doctor considers several other genuine causes of a fussy or crying baby, including an ear infection, nasal congestion, a hair or thread wrapped tightly around a tiny finger or toe (a "hair tourniquet," which is simple to check for and easy to miss), a reaction after a recent vaccination (see our Vaccine Side Effects article for what's expected there), reflux, or a possible cow's-milk-protein sensitivity. Reflux and milk-protein sensitivity in particular are genuine possibilities your pediatrician may consider, but they're not something to self-diagnose or manage at home by switching feeds on your own; both need an actual assessment, since over-attributing ordinary fussiness to either can lead to unnecessary feeding changes.
A careful history and a physical examination are usually enough to reassure that nothing more serious is going on. Colic is what's left once these have genuinely been considered, not the first explanation reached for.
Soothing strategies that genuinely help
- Swaddling snugly (with hips left free to move, and always placed on the back for sleep)
- Motion: gentle rocking, a stroller walk, or a car ride
- White noise or other steady, rhythmic sound
- Holding and skin-to-skin contact
- Gentle infant massage on the back or limbs
- A calm, dim environment, avoiding excessive noise, light, or handling, especially in the evening
- A predictable routine around sleep and settling, so your baby isn't overtired by the time you try to settle them
What doesn't help, or can be harmful
- Gripe water and similar over-the-counter drops have no consistent evidence of benefit, and some formulations carry sodium, sugar, or alcohol that aren't appropriate for a young baby; check with your pediatrician before using any.
- Simethicone drops (a common anti-gas remedy) have not been shown to work better than a placebo in trials.
- Fennel oil, dill oil, or digestive enzyme drops have no proven benefit.
- Traditional herbal preparations given by mouth (various household remedies fall into this category) are best avoided, since some carry real risks of choking, aspiration, or infection in a young infant.
- Dicyclomine, sometimes used historically for infant colic, is not recommended under 6 months of age because of a real risk of serious side effects, and should only ever be used if specifically prescribed and directed by a doctor.
- Probiotics (specifically Lactobacillus reuteri) have shown a reduction in crying time in breastfed babies with colic in some trials, though this strain is not routinely available in India, and evidence in formula-fed babies is weaker; this is worth discussing with your pediatrician rather than trying on your own.
- Switching formula repeatedly without medical guidance rarely helps and can make it harder to identify what's actually going on.
Red flags: when it isn't just colic
Most crying, even when it's intense and exhausting, doesn't signal anything dangerous. See your pediatrician promptly, rather than assuming colic, if your baby has:
- A high fever, or crying alongside any of the signs in our Signs Your Newborn Needs Urgent Medical Attention guide
- Difficulty feeding, or refusing feeds
- Unusual sleepiness or lethargy between crying spells
- Bilious (green) vomiting or blood in the stool
- Crying that is unusually high-pitched, doesn't follow the usual daily pattern, or is accompanied by a bulging soft spot
- Unexplained bruising, or reduced movement of an arm or leg
- Crying that continues to worsen, or is still severe, beyond about 4 months of age
A single hard evening isn't a red flag on its own; a pattern that includes any of the above is worth same-day medical attention rather than waiting it out.
Coping as a parent
This is genuinely one of the hardest parts of the newborn period, and it's worth saying plainly: a baby who won't settle, night after night, is exhausting in a way that's hard to describe until you've lived it. A few things are worth keeping in mind:
- It's normal to feel frustrated, and that feeling doesn't make you a bad parent
- If you feel yourself losing patience, it's safe and reasonable to place your baby on their back in a crib, step into another room, and take a few minutes to calm down
- Never shake a baby, under any circumstances. Shaking, even briefly, can cause serious, permanent brain injury. If you ever feel close to losing control, put your baby down safely and call someone, a partner, family member, or friend, to take over for a while
- Taking turns with a partner or family member, even for short stretches, makes a real difference
- Colic, by definition, resolves with time; it is not a sign that something is permanently wrong with your baby or your parenting

Frequently asked questions
Is it my fault if my baby has colic? No. Colic is not caused by anything a parent did or didn't do, and it isn't a reflection of parenting quality.
Should I switch to a different formula to fix colic? Not on your own. Repeated, unguided formula switching rarely resolves colic and can make it harder for your pediatrician to work out what's actually going on. Discuss this with your doctor first.
When will this stop? For most babies, colic-pattern crying eases significantly by around 3 to 4 months of age, even without a specific treatment.
