Fever / 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 / 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:

  • Becomes pale, mottled and feels abnormally cold to touch
  • Is going blue around the lips
  • Has a fit/ seizure
  • Becomes extremely agitated (crying inconsolably despite distraction), confused or very lethargic (difficult to wake)
  • Develops a rash that does not disappear with pressure (the ‘Glass Test’)






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 breath
  • Seems dehydrated (dry mouth, sunken eyes, no tears, drowsy or passing less urine than usual)
  • Is becoming drowsy (excessively sleepy) or irritable (unable to settle them with toys, TV, food or picking up) – especially if they remain drowsy or irritable despite their fever coming down
  • Has extreme shivering
  • Is under 3 months of age with a temperature above 38°C / 100.4°F (but fever is common in babies up to 2 days after they receive vaccinations)
  • Continues to have a fever above 38.0°C for more than 5 days
  • Is getting worse or if you are worried

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.

Where should you seek help?

For wear and tear, minor trips and everything in between.

Self-care

You can treat your child's very minor illnesses and injuries at home.

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.

Sound advice

Children can recover from illness quickly but also can become more poorly quickly; it is important to seek further advice if a child's condition gets worse.

For information on common childhood illnesses go to What is wrong with my child?

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 coughs, colds 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.

Sound advice

  1. Visit a pharmacy if your child is ill, but does not need to see a GP.
  2. Remember that if your child's condition gets worse, you should seek further medical advice immediately.
  3. Help your child to understand - watch this video with them about going to the pharmacy.

Health visitors are nurses or midwives who are passionate about promoting healthy lifestyles and preventing illness through the delivery of the Healthy Child Programme. They work with you through your pregnancy up until your child is ready to start school.

Health Visitors can also make referrals for you to other health professionals for example hearing or vision concerns or to the Community Paediatricians or to the child and adolescent mental health services.

Contact them by phoning your Health Visitor Team or local Children’s Centre.

Sound advice

Health visitors also provide advice, support and guidance in caring for your child, including:

  • Breastfeeding, weaning and healthy eating
  • Exercise, hygiene and safety
  • Your child’s growth and development
  • Emotional health and wellbeing, including postnatal depression
  • Safety in the home
  • Stopping smoking
  • Contraception and sexual health

School nurses care for children and young people, aged 5-19, and their families, to ensure their health needs are supported within their school and community. They work closely with education staff and other agencies to support parents, carers and the children and young people, with physical and/or emotional health needs.

Contacting the School Nurse

Primary and secondary schools have an allocated school nurse – telephone your child’s school to ask for the contact details of your named school nurse.

There is also a specialist nurse who works with families who choose to educate their children at home.

Sound Advice

Before your child starts school your health visitor will meet with the school nursing team to transfer their care to the school nursing service. The school nursing team consists of a school nursing lead, specialist public health practitioners and school health staff nurses.

They all have a role in preventing disease and promoting health and wellbeing, by:-

  • encouraging healthier lifestyles
  • offering immunisations
  • giving information, advice and support to children, young people and their families
  • supporting children with complex health needs

Each member of the team has links with many other professionals who also work with children including community paediatricians, child and adolescent mental health teams, health visitors and speech and language therapists. The school health nursing service also forms part of the multi-agency services for children, young people and families where there are child protection or safeguarding issues.

GPs assess, treat and manage a whole range of health problems. They also provide health education, give vaccinations and carry out simple surgical procedures. Your GP will arrange a referral to a hospital specialist should you need it.

Sound advice

You have a choice of service:

  1. Doctors/GPs can treat many illnesses that do not warrant a visit to A&E.
  2. Help your child to understand – watch this video with them about visiting the GP or going to a walk in centre
