Self care

Using the advice below you can provide the care your child needs at home

This guidance has been reviewed and adapted by healthcare professionals across Shropshire, Telford and Wrekin with consent from the Hampshire development groups.

  • Keep your baby/child as comfortable as possible. Consider giving paracetamol or ibuprofen for comfort
  • 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. How to take temperature
  • Keep an eye on your child day and night and follow the guidance overleaf
  • If a rash appears do “the glass test” (see guidance below)
  • 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

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

  • 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. Do not give more than the maximum daily dose of either medicine
  • However, remember that fever is a normal response that may help the body to fight infection and paracetamol/ibuprofen will not get rid of it entirely. Paracetamol and Ibuprofen bring down the temperature but do not treat the infection so whilst the child is unwell they will continue to get temperatures once the effects of the medication have worn off
  • 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, as they are of limited clinical effectiveness

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, whilst this doesn't mean your child is seriously unwell, please 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.
