Quick answer. A fever is a raised body temperature. It is a normal, protective response to an infection – most often a viral one – and the fever itself is usually not harmful and does not cause brain damage. How your child looks and behaves matters more than the exact number: a child who is alert, drinking and playing is reassuring even with a high reading. Home care is about comfort. The key exceptions are the red flags below – especially any fever in a young baby or newborn, which needs urgent medical review.

Few things worry parents more than a hot, unhappy child – but most fevers are the body doing its job. Knowing what to watch for lets you care calmly at home and act fast when it counts.
What a fever is
A fever is simply a body temperature that is higher than usual. It is not an illness in itself but a sign – usually that the body is fighting an infection. Raising the temperature is one of the ways the immune system works, so a fever is a normal and expected response, not something that is harming your child. The great majority of fevers in children are caused by ordinary viral infections that the body clears on its own over a few days.
Because a fever is a response and not the problem itself, fever medicines lower the temperature and ease discomfort but do not treat the underlying cause. A higher reading does not mean a more serious illness – your child’s overall behaviour and other symptoms tell you far more than the exact number. A child who is playing, feeding or drinking, and settling normally is reassuring even with a high temperature; a child who looks very unwell, listless or hard to rouse deserves attention whatever the reading.
Common causes
Most fevers come from common viral infections – coughs, colds, sore throats, ear discomfort, tummy bugs (vomiting and diarrhoea) and the usual run of childhood illnesses such as hand, foot and mouth disease. These typically get better by themselves with rest and fluids.
Sometimes a fever is caused by a bacterial infection, such as an ear infection or a urine infection, which may need review and sometimes antibiotics. Occasionally a fever follows a routine vaccination and settles quickly. In Singapore, it is also wise to stay alert to dengue, particularly during outbreaks or if there have been cases nearby – especially when a fever is persistent or comes with headache, body aches, a rash or vomiting. If you are unsure what is behind a fever, a doctor can examine your child and look for a cause; never try to diagnose the illness yourself from the temperature alone.
Caring for a feverish child at home
For most children, home care is about keeping them comfortable and hydrated rather than forcing the temperature down. Offer regular fluids in small, frequent amounts – breast or bottle milk for babies, water or their usual drinks for older children. Dress your child lightly and keep the room at a comfortable temperature; there is no need to bundle them up. Let them rest, and allow them to eat if they want to, without pressure.
Fever medicines such as paracetamol or ibuprofen can help if your child is distressed or uncomfortable. The goal is comfort, not to “chase” the number down to normal – a child who is happy and playing does not need medicine just because the thermometer is high. If you do use them, follow the correct dosing for your child’s age and weight, exactly as directed on the label or by a doctor or pharmacist, and check the timing between doses. Never give aspirin to a child with a fever, as it is linked to a rare but serious condition. For a very young baby, do not give any fever medicine without medical advice first.
You do not need to sponge your child with tepid or cool water, and cold baths are not recommended – they can make a child shiver and feel worse without helping, and they do not treat the illness.
What not to worry about, and what to watch
Some things that look alarming are usually normal. A feverish child’s hands and feet can feel cool even while the body is hot, and the cheeks may look flushed – on their own these are not danger signs. It is also common for a child to be off their food for a day or two.
What matters more is the overall picture. Keep an eye on your child’s alertness (are they rousable and interacting, or unusually drowsy and floppy?), their breathing (calm and easy, or fast, laboured or noisy?), their feeding and drinking, and their hydration – are they still passing urine and producing wet nappies, with moist lips and tears when they cry? A child who stays alert, drinks and wets nappies is generally doing well. A child who is becoming harder to wake, breathing with difficulty, or not drinking and drying up needs to be seen.
Fever in a very young baby
Fever is taken more seriously in a young baby, and most seriously of all in a newborn. Very young infants can become unwell quickly and show fewer obvious signs, so their bodies give less warning. For this reason, a fever in a young baby – and any fever in a newborn – should be reviewed by a doctor promptly, rather than watched at home. If your baby is in this age group and feels hot, arrange to have them seen without delay, and seek emergency care if any of the red flags above appear.
Febrile convulsions
Some young children can have a fit (convulsion) with a fever – known as a febrile seizure. It is very frightening to watch, but it is usually brief and not usually harmful, and it does not mean your child has epilepsy or has come to lasting harm. Fever medicines do not prevent these fits.
If it happens, stay calm and keep your child safe: lay them down somewhere they cannot fall or knock into anything, and gently turn them onto their side. Do not put anything in their mouth and do not try to restrain their movements. If you can, note the time the fit starts so you can tell how long it lasts, and seek medical advice afterwards so your child can be checked over. Call 995 for a first-ever fit, for a fit that is going on a long time or keeps coming back, or if your child is very unwell, is having trouble breathing, or does not recover normally afterwards.
When to see a doctor, and when it is an emergency
See a doctor – a GP or a paediatrician – if you are simply worried, if the fever is dragging on, if your child seems to be getting worse rather than better, if they have ear pain or pain passing urine, or if you are unsure what is causing the fever. It is always reasonable to have a feverish child assessed.
Treat it as an emergency – go to a Children’s Emergency or call 995 – for any of the red flags in the box above: a child who is very drowsy, floppy or not responding normally; a rash that does not fade when pressed; difficulty or fast, laboured breathing, or blue lips; a fit or convulsion; a stiff neck or dislike of bright light; signs of dehydration with poor drinking; a very high fever in a baby or any fever in a newborn; or whenever your instincts tell you something is seriously wrong.
Practical notes for Singapore
For a child who is otherwise well, your family GP or a polyclinic is a good first stop for assessment and advice, and many clinics can see feverish children on the same day. For anything urgent or an emergency – or for a very young baby or newborn with a fever – go to a Children’s Emergency department, such as those at KKH or NUH, or call 995. During dengue outbreaks, be extra alert to persistent or high fever with headache, body aches, rash or vomiting, and see a doctor early; watch for warning signs as the fever settles, including persistent vomiting, severe tummy pain, bleeding or unusual drowsiness, which need immediate review. HealthHub (MOH) has trusted, Singapore-specific guidance on caring for a feverish child. If you are ever unsure, it is always safer to have your child checked.
