What Time of Day Is Colic Worst?

Colic is worst in the early evening. The American Academy of Pediatrics puts the window between 6 p.m. and midnight, and describes colicky crying as often becoming worse at that end of the day. It’s one of the most consistent features of the condition — consistent enough that a baby who cries hardest at 7 a.m. is worth a second look.

The window, and how much of the day it takes

At the peak, around six weeks of age, the AAP puts the regular fussing at about three hours a day. Three hours landing between six and midnight is why the phrase “witching hour” exists and why it’s plural in practice.

The rest of the day is usually unremarkable. A colicky baby feeds, sleeps and settles normally in the morning, which is exactly what makes the evening so disorienting — it doesn’t feel like the same baby. That contrast is part of the picture, not a sign that something new went wrong at sunset.

Why the crying clusters there

No cause has been established for colic, and that includes the timing. What can be said is that the evening pattern is documented consistently across infants, and that several ordinary things converge in those hours:

• A day’s worth of accumulated stimulation with a nervous system still learning to filter it
• The transition into the longest sleep stretch, which newborns handle poorly
• The busiest, loudest part of the household day — dinner, older siblings, arrivals home
• The most depleted caregivers, which changes how the same crying is experienced

None of these is a proven mechanism. They’re the reasons the hour is hard even when the crying itself hasn’t changed.

The timing tells you something diagnostic

Because a hungry baby is hungry at any hour, and reflux tracks feeds rather than the clock, the concentration in one block is a genuine clue. A repeated evening pattern in a baby who is otherwise thriving fits colic; crying that follows every feed regardless of the hour fits something else. See colic vs hunger for the feeding test and colic symptoms for the full sign list.

Note also that newborns routinely cry 1 to 4 hours a day in total, per the AAP. Evening fussing is not automatically colic — the difference is intensity and how little soothing helps.

Plan the hours instead of enduring them

Knowing the window is the one practical advantage colic gives you:

1. Eat before it starts. Dinner at 5 p.m. beats attempting dinner at 7:30 with a screaming baby.
2. Schedule the handoff. Whoever gets home should take the baby immediately, not after changing clothes — trading off every 20 minutes is far more sustainable than one person absorbing all three hours.
3. Do the day’s chores before the window. Bottles, bath, laundry.
4. Get outside if you can. A walk with the stroller or carrier during the difficult hour works for some babies and, at minimum, changes the room you’re crying in.
5. Protect the night. The evening block is separate from normal night waking; see baby sleep hours by age for what to expect after it.

When the pattern breaks, call

Go to the pediatrician if the crying spreads across the whole day, if it starts abruptly in a baby who wasn’t crying like this before, or if it comes with fever, vomiting, refusal to feed or poor weight gain. A predictable evening pattern in a thriving baby is colic; an unpredictable one that takes over the day needs a look.
