My baby has a fever or high temperature

Fever in babies less than 90 days of age is much more likely to be due to a serious infection requiring urgent treatment compared to fever in an older child. For this reason, all children under 90 days of age with a temperature above 38°C or 100.4°F should be urgently reviewed by a healthcare professional. The only exception is if they have a fever in the 48 hours following their first set of vaccines (given at 8 weeks of age) – in this situation, it is OK to give them paracetamol without seeking medical advice if your baby is otherwise well. 

 

How to take your baby’s temperature:

You should measure your baby’s temperature under their armpit. Hold their arm against their body to keep the thermometer in place for however long it says in the manufacturer's instructions – usually about 15 seconds; some digital thermometers beep when they're ready. You should not measure their temperature on the forehead or in their ear – it will not be accurate in young children.

 

When should you worry?

If your child has any of the following:

  • Has blue lips 

  • Is pale, mottled and feels abnormally cold to touch 

  • Has pauses in their breathing lasting more than a few seconds, has an irregular breathing pattern or starts grunting 

  • Is too breathless to feed 

  • Is extremely agitated (crying inconsolably despite distraction), confused or very lethargic (difficult to wake) 

  • Is stiff or rigid or makes repeated, jerky movements of arms or legs that doesn't stop when you hold them (a fit or seizure) 

  • Develops a rash that does not disappear with pressure (the ‘Glass Test’) 

  • Is under 3 months of age with a temperature of 38°C or 100.4°F or above (unless fever in the 48 hours following vaccinations and no other red or amber features)  

You need urgent help

Go to the nearest Hospital Emergency (A&E) Department or phone 999

If your child has any of the following:

  • Is finding it hard to breathe 

  • Seems dehydrated (no tears, sunken soft spot on the head, drowsy or no wet nappies in the last 8 hours) 

  • Is becoming drowsy (excessively sleepy) or irritable (unable to settle them) – especially if they remain drowsy or irritable despite their fever coming down 

  • Is getting worse or if you are worried 

You need to contact a doctor or nurse today

Please call your GP surgery or contact NHS 111 - call 111.

If symptoms persist for 4 hours or more and you have not been able to speak to either a member of staff from your GP practice or to NHS 111 staff, recheck that your child has not developed any red features.

If none of the above features are present 

  • Watch them closely for any change and monitor for any red or amber symptoms

Self care

Continue providing your child’s care at home. If you are still concerned about your child, call NHS 111 – dial 111

What should you do?

  • Paracetamol can be given to children aged two months or older for pain or fever (ibuprofen can only be used above three months of age). However, fever in babies under 90 days of age can suggest a severe infection and they should be urgently reviewed by a healthcare professional. The only exception is if they have a fever in the 48 hours following their first set of vaccines (given at 8 weeks of age) – in this situation, it is OK to give them paracetamol without seeking medical advice if your baby is otherwise well. 

  • If a rash appears, do the glass test

Some illnesses can be treated in your own home with support and advice from the services listed when required, using the recommended medicines and getting plenty of rest.

Pharmacists are experts in many aspects of healthcare and can offer advice on a wide range of long-term conditions and common illnesses such as coughscolds and stomach upsets. You don’t need an appointment and many have private consultation areas, so they are a good first port of call. Your pharmacist will say if you need further medical attention.
