How to soothe a crying newborn: why babies cry and when to see a doctor

To soothe a crying newborn, work through the reasons babies cry, in order: offer a feed, burp, change the nappy, check whether your baby is too hot or cold, then try a quiet room, holding, gentle rocking and white noise. Most crying stops somewhere on that list. If your baby is fed, dry, comfortable and still crying hard for hours most evenings, it may be colic, which HealthHub says affects up to 1 in 4 babies and usually eases by 3 to 4 months. See a doctor the same day if the crying comes with a fever above 38 degrees Celsius, poor feeding, vomiting or unusual sleepiness.

Crying is how your baby talks before words exist, and in the early weeks there can be a lot of it. This guide gives you the checklist, the soothing steps that Singapore hospitals suggest, what colic is, how to take a safe break on the hard nights, and the red flags that mean it is time to call a doctor.

Why babies cry: the likely causes, in order

KKH doctors writing for HealthHub list seven common reasons a baby cries. Here they are in the order worth checking, with the signs each one gives and what to do.

Feel the tummy or the back of the neck to judge temperature. Hands and feet often feel cool even when your baby is warm enough, which matters in an air-conditioned Singapore bedroom.

How to soothe a crying newborn: a step-by-step checklist

Try one step, give it a few minutes, and move on if it is not helping. Staying calm is part of the method, because babies pick up on tension. Print this list and keep it by the cot for 3am.

NUH's advice for colicky babies adds two practical points: hold your baby for feeds and burp after each ounce of formula, or every five minutes when breastfeeding. If gentle motion has not settled your baby in about 20 minutes, NUH says it may be necessary to let them cry themselves to sleep. That is the moment to put your baby down safely and step away for a few minutes.

If you are breastfeeding, it is usually fine to offer a pacifier once feeding is well established. Our guide on when to stop swaddling covers swaddle safety in Singapore's heat.

What colic is, and when it passes

Some babies cry far more than the checklist can explain. Doctors call it colic when an otherwise healthy, well-fed baby cries for more than 3 hours a day, on more than 3 days a week, for over 3 weeks. That is the definition HealthXchange gives, with KKH's paediatricians.

• How common it is: HealthHub says up to 1 in 4 babies may have colic.
• When it starts: around 2 to 3 weeks old. HealthXchange says it peaks around 6 to 8 weeks.
• When it ends: most babies outgrow it by 3 to 4 months.
• What it looks like: intense crying that starts suddenly, often at the same time each late afternoon or evening, with legs curled up, fists clenched and a tight tummy. Many babies pass gas or open their bowels near the end of a bout.
• What causes it: nobody knows for sure. HealthHub notes that in fewer than 1% of cases a milk allergy is behind it.

Colic is distressing to live through, but it is not harmful to your baby and it is not your fault. Do not start cutting foods from your diet on your own. KKH's Dr Alison Snodgrass, writing in HealthXchange, says the evidence on diet changes is inconclusive and overly strict diets can harm both mother's and baby's nutrition. Talk to your doctor first.

Never shake a baby, and how to take a break safely

Relentless crying is one of the hardest parts of early parenthood, and feeling frustrated or close to tears yourself does not make you a bad parent. But there is one absolute rule: never shake a baby. Shaking can cause serious brain injury, blindness or death, even when it lasts only a moment.

• If you feel you are losing patience, put your baby down on their back in the cot and step away.
• Take a few minutes in another room to breathe or call someone. A crying baby in a safe cot is fine for a short while.
• Hand over to your partner, a family member, your confinement nanny or a friend so you can rest. HealthHub says there is no embarrassment in asking for help.
• Go back when you feel steadier.

Looking after yourself

Sleep loss and constant crying take a toll. Persistent low mood, anxiety, hopelessness, or feeling disconnected from your baby can be signs of postnatal depression, which is common and treatable. HealthHub has a free postnatal depression self-check, and our guide to postnatal depression help in Singapore lists who to call. Our newborn care basics guide covers building gentle routines in the early weeks.

When crying needs a doctor

Most crying is normal. These signs mean you should see a doctor promptly, the same day:

• A cry that sounds different from usual, such as weak, high-pitched or moaning, or crying that nothing soothes.
• Fever: HealthHub says a baby who is crying persistently, shows signs of illness and has a temperature above 38 degrees Celsius should see a doctor immediately. In a baby under 3 months, any fever needs a prompt check.
• Feeding poorly, or far fewer wet nappies than usual.
• Vomiting, diarrhoea or blood in the stools.
• Lethargy: unusually sleepy, floppy or hard to wake.
• Constant crying for more than three hours, or a baby who seems to be in pain.

Go to a children's emergency department straight away for breathing difficulty, blue lips, a seizure, or a baby you cannot wake. Our guide on baby fever and when to worry explains the temperature thresholds in detail.

Where to get help in Singapore

Your paediatrician or polyclinic doctor can review your baby and rule out medical causes, such as an ear infection or a hernia, before calling it colic. For advice at night, KKH runs the Urgent Paediatric Advice Line (U-PAL), a free online service open 24 hours for parents of children under 18. It answers questions on fever, vomiting and breastfeeding. For anything urgent, KKH and NUH both run children's emergency departments. Lactation consultants and parent support groups can help with feeding and coping.

Frequently asked questions

How do you soothe a crying newborn fast?

Go through the basics in order: feed, burp, nappy, temperature. If those are fine, hold your baby close in a quiet, dim room and add rhythm: rocking, swaying, a walk in a carrier or a steady white noise like a fan. Swaddling and a pacifier help many newborns.

How long should I let my baby cry before picking them up?

In the newborn months there is no need to wait. Responding to your baby's cries does not spoil them. The only time to step back on purpose is if you feel overwhelmed; then put your baby down safely and take a short break.

Is colic dangerous?

No. In an otherwise healthy, growing baby, colic does no harm and usually settles by 3 to 4 months. Crying with fever, vomiting, poor feeding, diarrhoea, blood in the stools or lethargy needs a doctor, because those point to another cause.

Why does my baby cry more in the evening?

Colicky crying often comes at the same time each day, usually late afternoon or evening. Tiredness and stimulation build up over the day. Dim the lights, cut the handling, and use gentle motion or white noise to get through it.

Is white noise safe for a newborn?

Generally yes, at a low volume with the source away from your baby's head and cot. KKH's paediatrician notes in HealthXchange that some babies quieten to the sound of a washing machine or fan.

Could my baby be crying because of something in my breast milk?

Usually not. A cow's-milk protein allergy can cause excessive crying along with vomiting, rashes or blood in the stool, but HealthHub puts milk allergy behind fewer than 1% of colic cases. Speak to your doctor before cutting foods out.

This guide is general information for Singapore parents and is not medical advice. If your baby shows any of the red flags above, or you are worried, see a doctor promptly. And on the hard nights: never shake a baby, it is okay to put your baby down safely and take a break, and you are not alone.
