Newborn Witching Hour: Why It Happens and When It Ends

It's a little after 6 p.m. The day was going fine. Then, almost on cue, your baby starts to cry — and nothing that worked this morning works now. A feed buys you five minutes. The bounce that always calms them does nothing. By the time your dinner has gone cold, you're quietly wondering what you're doing wrong.

Parents call this the witching hour. Pediatricians call it normal. If your baby melts down at roughly the same time every evening, you're not imagining the pattern, you didn't cause it, and it almost never means something is wrong. Here's what's actually happening, how to tell it apart from colic, what tends to help, and — just as important — when it ends.

01What the newborn witching hour actually is

The witching hour is the informal name for a predictable stretch of evening fussiness in young babies. Despite the name, it's rarely just one hour. The American Academy of Pediatrics notes that a young baby's regular fussy periods tend to happen "between 6 p.m. and midnight" (HealthyChildren.org), and Cleveland Clinic describes the same rhythm: the crying "usually starts suddenly at about the same time every day," most often in the afternoon or evening (Cleveland Clinic).

The key word is normal. Cleveland Clinic describes this evening crying as "a normal phase in a baby's development" — not an illness, not a feeding failure, and not a reflection of your parenting (Cleveland Clinic). Even healthy, well-cared-for babies "may cry for 1 to 2 hours every day," because crying is the only way they have to express their needs (HealthyChildren.org).

02When it starts, when it peaks, and when it ends

Evening fussiness follows a well-documented arc that researchers call the crying curve. It typically begins around 2 weeks of age (Cleveland Clinic) and builds from there. The AAP notes that normal fussing usually peaks at about 3 hours a day by 6 weeks old (HealthyChildren.org), and Cleveland Clinic puts the peak in the second month of life — so if you're deep in it at 6 to 8 weeks, you are likely standing at the top of the mountain, not the bottom.

Then it recedes. Daily fussing typically drops to 1 or 2 hours a day by 3 to 4 months of age (HealthyChildren.org), and the whole crying-peak phase generally wraps up somewhere between 3 and 5 months (Cleveland Clinic). This is a season with an end date, measured in weeks — not the new permanent shape of your evenings.

03Witching hour, colic, or PURPLE crying?

These three labels get used interchangeably, and honestly, they overlap a lot — Cleveland Clinic points out that "purple crying," colic, and the witching hour are often different names for the same normal phase (Cleveland Clinic). But the distinctions are worth knowing, mostly because they change how worried you should be. (Spoiler: not very.)

Colic: the rule of threes

Colic is the label doctors use when an otherwise healthy baby's crying crosses a specific threshold: more than 3 hours a day, at least 3 days a week, for more than 3 weeks (Cleveland Clinic). About one-fifth of babies develop colic, usually between the second and fourth weeks of life, and colicky babies tend to cry inconsolably — often screaming, extending or pulling up their legs, and passing gas (HealthyChildren.org). Colic peaks between 4 and 6 weeks and "usually ends rather abruptly" at 3 to 4 months (Cleveland Clinic), though the AAP notes it can occasionally last until 6 months (HealthyChildren.org).

The Period of PURPLE Crying

The Period of PURPLE Crying is a program from the National Center on Shaken Baby Syndrome, built on more than 50 years of research on normal infant crying. Its whole point is reframing: this crying peak happens in normal, healthy infants, and understanding that protects both babies and exhausted parents. The PURPLE acronym describes the features (Cleveland Clinic): Peak of crying (it builds, crests around month two, then tapers), Unexpected (crying comes and goes for no apparent reason), Resists soothing (nothing reliably stops it), Pain-like face (your baby can look like they're in pain even when they're not), Long-lasting (some babies in this period cry 5 hours a day or more), and Evening — the crying clusters in the late afternoon and evening. That last letter is your witching hour.

The practical takeaway: the witching hour is the evening slice of a normal crying curve. Colic is the label applied when the total amount is extreme. Either way, evening crying by itself — without the red flags below — is something to mention at your next checkup, not an emergency.

04Why evenings hit so hard

Nobody has pinned down a single cause, and anyone who tells you otherwise is selling something. But a few documented contributors stack up at the end of the day:

• Overstimulation. The AAP notes that some fussy babies are "unusually sensitive to stimulation" and can't yet self-console or regulate their nervous system (HealthyChildren.org); Cleveland Clinic lists sensory overload among possible colic contributors (Cleveland Clinic). By evening, a newborn has absorbed a full day of light, noise, faces, and handling.
• Swallowed air and gas. A day's worth of feeding means a day's worth of swallowed air, which Cleveland Clinic lists as a possible source of discomfort (Cleveland Clinic).
• Evening cluster feeding. More frequent feeds at certain times of day — especially evenings — are normal. Prolactin, the milk-making hormone, is usually lowest in the evening, so breastfed babies may feed in short, close-together bursts to compensate (Cleveland Clinic). A baby who is asking to eat again is easy to mistake for a baby who is inconsolable.
• The crying curve itself. Crying peaks around 6 to 8 weeks, and it concentrates in the evening — that's the E in PURPLE (Cleveland Clinic). Some evenings, the crying is simply the age your baby is.

If your baby wants to nurse on and off all evening, that's usually cluster feeding — a normal pattern, not proof your milk supply is failing (Cleveland Clinic). We cover how to survive those marathon evenings in our cluster feeding guide.

05What actually helps

There's no magic move, but there is a sensible order of operations. Work through it slowly — one change at a time, in a dim, quiet room — rather than cycling frantically through everything at once.

Set your expectations honestly: the PURPLE crying program is blunt that soothing methods "may work some of the time, but nothing will work ALL of the time" (Period of PURPLE Crying). A trick failing tonight doesn't mean it's useless tomorrow, and crying that keeps going doesn't mean you did it wrong.

06What you don't need to fix

You don't need to get the crying to zero. Healthy babies cry — 1 to 2 hours a day is within normal even for well-loved, well-fed babies (HealthyChildren.org). You don't need to fix your milk supply because your baby feeds constantly at 7 p.m. — evening clustering is an expected pattern, not a shortage (Cleveland Clinic). And you don't need to find the one root cause, because this phase resolves on its own timetable: colicky crying "usually ends rather abruptly" around 3 to 4 months (Cleveland Clinic).

A baby crying in your arms while you do everything right is not a problem you're failing to solve. Sometimes it's just Tuesday, at 6 weeks old.

07Take care of the person holding the baby

The witching hour lands at the exact moment your own tank is empty — end of day, dinner not made, sleep debt compounding. Treat evenings as a two-person job whenever you can: run shifts, trade the baby every 30 to 45 minutes, and let the off-duty person actually leave the room. The AAP's advice for tense, anxious moments is to have a family member or friend take the baby and to get out of the house for a bit (HealthyChildren.org).

If there's no backup adult at your house in the evenings, that is exactly the gap professional overnight newborn help exists to fill — you can browse vetted options in our night help directory. Even one or two covered evenings a week changes how survivable the peak weeks feel.

08It ends

Here's the part to hold onto at 8 p.m. tonight: this peaks around 6 to 8 weeks and typically fades by 3 to 4 months (HealthyChildren.org) — often ending surprisingly abruptly (Cleveland Clinic). One evening you'll realize dinner happened, the lights stayed on, and nobody cried — possibly including you. Until then: dim the lights, run the sequence, trade shifts, and put the baby down safely when you need a breather. You're not doing it wrong. You're doing the hardest weeks.
