Prevent heat related illness - advice for babies and young children

Babies and young children are more susceptible to heat-related illness than adults because their bodies cannot easily adapt to changing temperatures. The younger the child, the quicker they will start to show signs of dehydration or heat stress.

Parents or carers need to be aware of weather conditions in which heat-related illness is likely and take precautionary measures.

If hot weather is predicted or present:

Stay hydrated and well nourished

  • Give children plenty of water, before they become thirsty. Avoid using ice
  • Do not give children drinks that cause dehydration - such as drinks high in sugar, salt and/or caffeine
  • If you are breastfeeding, feed your baby more often and drink plenty of water yourself
  • Give bottle-fed babies cool, boiled water between feeds
  • Give children small regular meals and minimise hot food
  • Monitor your child’s urine output:
    • babies - monitor the number of wet nappies. If your baby has fewer wet nappies than usual in a 24 hour period, see a doctor or ring 13 HEALTH for advice
    • young children - urine should be a light straw colour. Dark urine may be a sign of dehydration and indicate the need to drink. If you are concerned you should seek advice from your doctor

Stay cool

  • Dress children in loose fitting, single layered, cotton clothing
  • Keep children cool by giving them regular lukewarm baths or showers. Do not use ice cold water
  • Keep your home cool or go to cool areas, such as air conditioned buildings or shopping centres
  • Avoid taking your child outside between 10am - 3pm
  • Ensure you use a suitable sunshade on your baby's stroller
  • Ensure children wear broad-brimmed hats and SPF 30+ to avoid sunburn
  • Be aware of any pre-existing medical conditions, which may cause a child to be more heat-sensitive

Caring for children in heat

  • Children may experience nappy rash when it is hot - avoid using talcum powder, keep area clean and dry
  • Sick children need special attention in hot weather, even for minor illnesses such as a cold or hay fever

Never leave children unattended in hot cars.

Be alert for the early signs of heat stress:

  • rising body temperature
  • dry mouth and eyes
  • headache
  • shortness of breath
  • vomiting
  • absence of tears when crying.
