Why Is My Baby Crying? Understanding Newborn Crying and How to Cope

At 2 a.m., after another feed, nappy change, burp and cuddle, it can feel as if the crying will never end. You may be asking yourself, “Why is my baby crying?” or even wondering whether you are missing something obvious.

You are not failing. You are not “making a rod for your own back”. And, in most cases, you are not doing anything wrong.

Newborn crying can be intense, repetitive and genuinely exhausting. Yet there is a well-known developmental pattern behind it. For many families, the hardest weeks come before things begin to ease. There really is a light at the end of the tunnel.

The normal newborn crying pattern

Most babies cry more as the first weeks go by. That surprises many new parents. You might expect a newborn to be at their noisiest straight after birth, then gradually settle. Usually, the opposite happens.

A typical normal newborn crying pattern looks something like this:

• Crying begins at a relatively low level in the first days after birth.
• It increases steadily over the first several weeks.
• Baby crying peaks at 6 weeks, often between 6 and 8 weeks.
• At the peak, babies may cry or fuss for an average of 2 to 3 hours a day.
• Crying then gradually reduces.
• By around 3 to 4 months, most babies cry significantly less and are easier to settle.

So, how long do newborns cry? It varies hugely. One baby may cry for 45 minutes across a whole day; another may have several long unsettled stretches. The average figures do not mean every baby follows the same timetable. They do show that a very fussy baby in the early weeks is not automatically a baby with a medical problem.

If you are in the thick of it, this can feel like a small comfort. Three hours is still a very long time when you are tired, touched out and trying to drink a cup of tea before it goes cold. But the shape of the curve matters: it rises, peaks, then comes down.

When will baby cry less?

The short answer? Usually sooner than it feels right now.

For many babies, parents notice the first meaningful improvement around 10 to 12 weeks. The evenings may become less explosive. Your baby may spend more time quietly alert, looking at your face or kicking contentedly on a play mat. Settling might still take effort, but it no longer feels impossible.

By 3 to 4 months, most babies have moved well past the most intense phase of newborn crying. They are not necessarily silent, of course. Babies still cry when they are hungry, tired, overstimulated or cross about being put down. But the long, baffling, hard-to-soothe crying spells tend to become much less common.

That is why the answer to “when will my baby stop crying?” is not a single date. Babies do not stop communicating through crying. What changes is the amount, the intensity and your ability to read what they need.

The Period of PURPLE Crying explained

You may hear health visitors, midwives or infant-crying resources talk about the Period of PURPLE Crying. Despite the name, it does not mean a baby turns purple while crying. It is a term used to explain a normal stage of early infancy when crying can feel especially difficult and unpredictable.

PURPLE is an acronym:

• P - Peak of crying: Crying rises week by week, usually peaking around 6 to 8 weeks.
• U - Unexpected timing: Crying can start and stop without an obvious reason.
• R - Resists soothing: The usual tricks may not work, even when you are doing everything “right”.
• P - Pain-like face: A baby can look as though they are in pain, with a red face, clenched fists and drawn-up legs, even when they are physically well.
• L - Long-lasting: Some crying bouts can last a long time.
• E - Evening clustering: Crying often bunches up late in the day.

This is normal developmental behaviour, not proof that your baby is unhappy with you, that your milk is inadequate, or that you have caused a problem by cuddling too much.

The phrase can be especially helpful because it gives a name to that awful experience of trying everything. Feed. Burp. Change. Rock. Sing. Walk. Repeat. And still, your baby cries.

Sometimes there is no neat fix. That is hard, but it is not your fault.

Is it colic, or normal baby crying?

The word colic is often used when a baby cries for long periods, particularly in the evening. Traditionally, colic has been described as crying for more than three hours a day, on at least three days a week, for three weeks or more in an otherwise healthy baby.

In real life, the boundary between colic and normal newborn crying is not always clear. Many babies who are labelled “colicky” are moving through the ordinary crying curve, just at the more intense end of it.

Colic is not a sign that a baby is being difficult. Nor is it a diagnosis that tells you exactly what to do. There is no single proven cause. Gut discomfort may play a part for some babies, but crying is also closely tied to brain and nervous system development.

If your baby is feeding well, gaining weight, having regular wet nappies and seems well between crying episodes, the peak crying period is often the explanation. Still, trust your instincts. You know your baby best.

Why is evening crying newborn behaviour so common?

For many families, late afternoon arrives with a sense of dread. Your baby who seemed fairly settled at 11 a.m. may become inconsolable from 5 p.m. onwards. This is often called the “witching hour”, though it can last several hours.

Why do babies cry more in the evening? There are a few theories:

• Sensory overload: A newborn’s brain is processing a whole day of sounds, lights, movement, faces and handling. By evening, it may all be too much.
• Tiredness: Babies can become overtired quickly, and overtired babies often struggle to settle.
• Normal hormone rhythms: Some experts suggest changes in cortisol and other daily rhythms may contribute, though this is not fully proven.
• Evening milk patterns: Breastfed babies often feed more frequently in the evening. Milk flow and supply can feel different later in the day, and cluster feeding is common. This does not usually mean you do not have enough milk.

The truth is that no one explanation fits every baby. An evening crying newborn may simply be showing a very normal pattern of immature regulation.

Try to lower the demands of that part of the day if you can. Dim the lights. Keep visits short. Have an easy dinner ready. Let the washing wait. For a few weeks, survival mode is a valid household management strategy.

The science: your baby’s nervous system is still learning

Crying is one of the first ways babies communicate, but it is also part of nervous system maturation.

A newborn cannot yet regulate their feelings or body state as an older baby can. They cannot calm themselves by changing position, reaching for a comfort object, taking a deep breath or understanding that discomfort will pass. Everything is immediate. Hunger feels huge. Tiredness feels huge. A noisy room can feel huge too.

As the brain matures, babies gradually develop better self-regulation. Their sleep-wake rhythms become more organised. Digestion often settles. They become better able to cope with stimulation and, eventually, to use you as a secure base for calming down.

That is why the crying curve improves with time. Not because you finally discover one magic swaddle, white-noise track or bouncing technique. Those things can help, certainly. But a big part of the change is developmental. Your baby is growing into it.

How much do newborns cry, according to the data?

Studies of infant crying across several countries show a similar broad trend: crying increases after birth, peaks in the first two months, then declines. The exact average differs between studies because researchers measure crying and fussing in slightly different ways.

The reassuring finding is the direction of travel. Most babies show dramatic improvement between weeks 10 and 12.

That does not mean week 12 arrives and every difficult evening disappears overnight. Progress can be uneven. You may get two calmer days, then a rough one. But when you track the bigger picture over a couple of weeks, rather than judging each individual night, the shift often becomes clearer.

How to soothe baby during the peak crying weeks

You do not need to solve every cry. Sometimes the goal is simply to support your baby and get through the next ten minutes.

A few approaches can help:

• Offer a feed if your baby shows hunger cues. Evening cluster feeding is normal, especially for breastfed babies.
• Hold your baby close, skin-to-skin if that feels right for both of you.
• Try rhythmic movement, such as a walk with the pram, a baby carrier walk, gentle rocking or pacing around the room.
• Use steady sound. A quiet shushing noise, running water or low-level white noise may help.
• Change the scene. Step outside for fresh air, stand by an open door or walk around the block.
• Check the simple things: nappy, temperature, clothing, wind, hunger and tiredness.
• Keep stimulation low in the evening. Fewer bright lights and fewer people passing baby around can make a difference.

Some babies settle best in arms. Others seem to prefer movement. One might relax in a carrier while another protests until they are taken outdoors. There is no universal answer to how to soothe baby. You are allowed to experiment.

You need care too

A crying baby can push even the most patient parent to their limit. If you feel angry, panicky, tearful or numb, that does not make you a bad parent. It means you need support.

Make a plan before you reach breaking point:

1. Take shifts with a partner, family member or trusted friend. Even 30 uninterrupted minutes can reset your nervous system.
2. Call someone. A friend, your health visitor, GP surgery or local postnatal support service can be a lifeline on a hard day.
3. Use earplugs at a reduced volume while you hold your baby safely. You can still respond to them, but the sharpness of the sound is softened.
4. Put your baby down safely in their cot or Moses basket and step away briefly if you feel overwhelmed. Take a few slow breaths, drink water, stand in another room for a moment.
5. Never shake a baby. If you are frightened by your own feelings, place your baby somewhere safe and get help immediately.

If you are in the UK and need urgent medical advice, contact NHS 111. Call 999 if your baby is struggling to breathe, turns blue or grey, is floppy or unresponsive, has a seizure, or you believe they need emergency care.

When to seek medical advice about baby crying

Most newborn crying is normal. Still, contact your GP, midwife, health visitor or NHS 111 if your baby’s crying feels different or you are worried.

Seek advice promptly if your baby has:

• A fever of 38°C or higher if they are under 3 months old
• Difficulty breathing, blue or grey lips, or unusual limpness
• Repeated forceful vomiting, green vomit, or blood in vomit or poo
• Poor feeding or noticeably fewer wet nappies
• A high-pitched, weak or very unusual cry
• A swollen abdomen, rash, or signs of injury
• Crying that is suddenly much worse than usual

You never need to “wait it out” just because someone called it colic. Reassurance is helpful, but so is being listened to.

Track the curve, not just the hard day

During a rough week, it is easy to believe nothing is changing. Tracking feeds, sleep and crying in the Erby app can give you a wider view. Note when crying starts, how long it lasts, what you tried and whether there is a pattern around evenings, feeds or naps.

After two or three weeks, many parents can see small changes they had missed: crying starts later, the longest spell is shorter, or there are more calm pockets in the day. That evidence can be deeply reassuring when you are wondering, “When do babies cry less?”

Your baby is not giving you a test you are failing. They are having a hard moment in a brand-new nervous system, and you are their safe place through it.

This phase is temporary. Your baby will cry less. You will not always feel this tired. And you are doing far better than you think.
