Self care

Continue providing your child’s care at home using the advice below. If you are still concerned about your child, speak to your health visitorlocal pharmacist or call NHS 111– dial 111. Keep monitoring your child for red and amber features and seek help if they develop

How can I look after my child?

  • Keep monitoring your child for red and amber features (see above). Seek help if they develop, as this may suggest a more severe illness requiring specific investigations and treatment.
  • Keep your baby/child as comfortable as possible. Consider giving paracetamol or ibuprofen for comfort. 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).
  • Offer them simple food and regular drinks. Where a baby is breastfed, continue breast feeding.
  • If they are vomiting, offer small frequent drinks as this is more likely to stay down.
  • Do not try to control your child’s temperature with tepid sponging or fans.
  • If a rash appears do “the glass test” (see guidance overleaf).
  • Fever is common in babies up to 48 hours after receiving immunisations - consider giving regular paracetamol. If your child is due their vaccinations, postpone until after their fever has improved.
  • If you need to keep your child away from nursery or school while they are unwell and have a fever please notify the nursery or school – see www.what0-18.nhs.uk for advice if you are unsure.

About fever in children

Most children with a fever do get better very quickly but some children can get worse. You need to regularly check your child during the day and also through the night and follow the advice given below.

  • Fever is extremely common in children and usually suggests that your child has an infection.
  • Your child has a fever if their temperature is over 38°C. The most accurate way of measuring your child’s temperature is with a digital thermometer.
  • Viral infections are far more common than bacterial infections. Symptoms such as runny nose, cough, wheeze, sore throat, red eyes and diarrhoea are more suggestive of a viral infection than a bacterial infection. If a number of people are unwell in the same household, this also suggests a viral infection (because viral infections are easily spread).
  • Viral infections tend to get better on their own and do not need treatment with antibiotics.
  • During a viral illness we would expect to see ongoing temperatures for 2-3 days and then a slow and gradual improvement of symptoms. If your child becomes more unwell after a period of initial improvement, then seek medical input.

Using medicines to help

  • If your child is distressed you should consider giving them paracetamol or ibuprofen to help them feel more comfortable. Use one and if your child has not improved 2-3 hours later you may want to try giving the other medicine.
  • Carefully read the instructions on the medicine for dose and frequency.
  • You could ask your local pharmacist for more advice about medicines.
  • In general, we do not recommend cough medicines.

The Glass Test

Do the ‘glass test’ if your child has a rash. Press a glass tumbler firmly against the rash. If you can see the spots through the glass and they do not fade as you press the glass onto the skin then this is called a ‘non-blanching rash’. If you see this type of rash, seek medical advice immediately. The rash is harder to see on dark skin so check paler areas, such as palms of the hands, soles of the feet and tummy.
