Your 3-week-old cries every evening: is this normal?

Evening crying usually starts between 2 and 4 weeks, peaks at 6 to 8 weeks and eases by 3 to 4 months. Here's why it happens, how to check feeding is on track and what helps.

After two sleepy weeks, your 3-week-old has started a new routine. From late afternoon until nearly midnight they cry on and off between feeds, and no one can settle them.

It's one of the most common newborn patterns, and the timing is right on schedule. Evening crying usually starts between 2 and 4 weeks, builds until about 6 to 8 weeks, then fades bit by bit. If your baby feeds well, fills plenty of wet diapers (nappies) and is gaining weight, the crying is rarely a sign of trouble.

Why do evenings fall apart at 3 weeks?

All day your baby takes in light, noise and a lot of handling, and a newborn's nervous system can't wind down on its own yet. By evening it spills over, often between about 6 p.m. and midnight.

Crying for an hour or two a day with no obvious cause is normal for a healthy baby. When it tops three hours a day, several days a week, the medical name is colic. Colic describes the crying pattern and isn't an illness. It follows the same timeline.

Is my baby hungry, or is it cluster feeding?

Many babies want the breast or bottle again and again through the evening, often during a growth spurt, then sleep longer. Cluster feeding like this is normal. It usually doesn't mean low milk supply, even when your breasts feel softer by nighttime.

Frequent feeds alone don't tell you much. Count diapers instead: from around day 5, expect at least six wet ones a day, along with steady weight gain at checkups. With formula, follow your baby's cues to stop and don't push them to drain the bottle.

How to get through the fussy hours

Some nights nothing works, and that's not your fault. Try:

  • Turn the lights down and feed in a quiet room.
  • Walk the halls with your baby held close, skin to skin or in a carrier.
  • Swaddle (wrap) your baby and switch on white noise. Stop swaddling as soon as your baby starts trying to roll.
  • Give a warm bath, rock slowly or offer a pacifier (dummy).
  • Trade shifts with your partner or another helper.

What other parents say

The crying tends to start out of nowhere after two sleepy weeks, at the same hour each evening. Most babies settle best when held close, whether in a carrier, on a walk outside or in your arms as you bounce gently on an exercise ball. Putting your baby down for a nap shortly before the fussy hour can soften it. Many parents notice it easing gradually after about 8 weeks. If it's still going strong at 3 months, read about evening fussiness at 3 months.

When to get help

Don't wait to call your pediatrician or doctor if your baby:

  • runs a fever of 100.4°F (38°C) or higher. Any fever before 3 months is urgent.
  • is feeding poorly, turning down feeds or wetting fewer diapers
  • vomits, particularly if it's forceful or green
  • has a cry that sounds weak, high-pitched or unusual
  • cries differently from the usual evening pattern, or nonstop for over 2 hours

If you hit a breaking point, lay your baby on their back in the crib (cot), step out of the room and give yourself 10 to 15 minutes before going back in. Never shake a baby.

For everyday questions, call your pediatrician or doctor (UK: GP or NHS 111; Australia: healthdirect 1800 022 222; Canada: 811 in most provinces). If your baby is floppy, hard to wake or struggling to breathe, call 911 (US and Canada), 999 (UK), 000 (Australia), 111 (New Zealand) or 112 (Ireland).

The bottom line

Crying every evening at 3 weeks is the start of a phase most babies go through. Go by diapers and weight to judge feeding, and when an evening drags on, let someone else take a turn.

FAQ

When will the evening crying end?

Most babies hit the peak at about 6 to 8 weeks, and the crying eases off by 3 to 4 months. A few keep it up until around 6 months.

Is cluster feeding a sign of low milk supply?

Usually not. If the wet diapers keep coming and your baby gains weight steadily, they're getting enough.

Should I switch formula or change what I eat?

Talk to your doctor before you change anything. Something in a breastfeeding parent's diet (or, less often, a protein in formula) can play a part, but usually nothing needs to change.
