What are the most common reasons a newborn cries?

The most common reasons are hunger, a dirty or wet nappy, tiredness or over-stimulation, wind or needing to burp, being too hot or cold, and simply wanting comfort or closeness. Crying is a newborn's main way to communicate a need — it is normal and expected.

How can I tell why my baby is crying?

Work through the likely reasons in order: when did they last feed, how long have they been awake, when was their last nappy change, and could they be too warm or cold? Recent patterns are the best clue — for example, if it has been about three hours since a feed, hunger is more likely. It is often trial and error, and that is normal.

Is it normal for a newborn to cry a lot in the evenings?

Yes. Many babies have a fussy, harder-to-settle period in the late afternoon and evening in the first few months, often peaking around 6 weeks and easing by 3–4 months. If crying is intense and frequent, mention it to your doctor to rule out other causes.

Why is my newborn crying? The common reasons — and how to tell

Q: When should I worry about my baby's crying?

Contact a professional if the cry sounds unusually high-pitched, weak, or continuous and nothing soothes it; if it comes with a fever, poor feeding, vomiting, a rash, or unusual sleepiness; or if your instinct simply tells you something is wrong. Trust that instinct. In an emergency, call your local emergency number.

A calm, practical guide to the most common reasons newborns cry — hunger, tiredness, discomfort, and more — plus how to work through them and when to call your doctor.

In the first weeks, crying is your baby's only real language. It isn't a sign you're doing anything wrong — it's how a newborn says “I need something.” The hard part is that the message is the same sound for very different needs. Here's a calm way to work through the common reasons.

Start with the basics, in order

Most newborn crying comes down to a short list. Running through it in order solves the majority of moments:

Hunger. The most common reason in the early weeks. If it's been roughly 2–3 hours since the last feed — or you spot early cues like rooting, hands to mouth, or lip-smacking — try offering a feed first.
A dirty or wet nappy. Quick to check, quick to fix.
Tiredness or over-stimulation. Newborns can only stay comfortably awake for short windows (often under an hour). Past that, they get wired rather than sleepy and cry. A calm, dim, quiet space helps.
Wind or needing a burp. Especially during or after a feed. Hold them upright and gently pat or rub their back.
Too hot or too cold. Feel the back of the neck or chest — not hands and feet, which are normally cooler. Adjust a layer.
Wanting comfort. Sometimes the need is simply closeness — holding, skin-to-skin, gentle rocking, a calm voice, or a dummy if you use one.

Use what just happened as your clue

The single most useful thing when decoding a cry is context: the timeline of the last feed, the last sleep, and the last nappy. If your baby fed 20 minutes ago, hunger is unlikely and wind or tiredness moves up the list. If they've been awake for well over an hour, an overtired baby is the strong candidate. This is exactly the reasoning EVE's CrySense does for you — it weighs your recent records to rank the most likely reasons, so you're not guessing blind at 3am. It's a starting point to check, never a diagnosis.

Soothing techniques worth trying

Once the basic needs are met, these calm many newborns: holding them skin-to-skin, gentle rhythmic rocking or a walk, a quiet shushing sound or white noise (which echoes the womb), a warm calm room, and secure — not tight — swaddling if your baby likes it. Babies are individuals; you'll learn your own baby's favourites over the first weeks.

Looking after yourself matters too

Persistent crying is genuinely exhausting, and it can make you feel helpless. If you ever feel overwhelmed, it is completely okay to lay your baby down somewhere safe (like their cot), step away for a few minutes to breathe, and come back. A calm parent soothes more effectively than a frazzled one — and asking for help is a strength, not a failure.

When to seek advice

Trust your instincts. Contact your doctor, nurse, or health visitor if the cry is unusually high-pitched, weak, or relentless and nothing soothes it; if it comes alongside a fever, poor feeding, vomiting, a rash, or unusual sleepiness; or if you simply feel something isn't right. You know your baby. In an emergency, call your local emergency number straight away.
