Heatwave precautions for babies & young children

Anyone can suffer from heat-related illness.

Those most at risk are: 

  • babies and young children     
  • pregnant and nursing parents 
  • people who are physically unwell, especially with heart disease, high blood pressure or lung disease 
  • people on medications for mental illness
  • people over 65 years.

What to look for

Babies and young children should be watched carefully during hot weather. They can quickly lose body fluids through perspiring, which can lead to dehydration. They need to drink regularly, wear light clothing, and be kept cool. 

Babies and young children may not show early signs and symptoms of the effects of heat. They may just look unwell or be more irritable than usual. Babies may seem floppy, have drier skin, and refuse to drink, or have fewer wet nappies than usual. The soft spot on top of a baby’s head (fontanelle) may also be lower than usual.

Steps to keep babies safe during the extreme heat

  • During hot weather, breastfed babies may need extra breastfeeds. If you are breastfeeding, you don't need to give a very young baby extra water during a heatwave as the breast milk provides your baby with all they need. You should, however, make sure you drink plenty of fluids. 
  • Don’t leave babies to sleep in a pram in hot weather – prams can be hot and airless; make sure air can circulate around your baby – for example:
    • remove any padding around your baby's cot
    • cover mattresses and waterproof sheets with thick layers of cotton sheets to absorb perspiration and prevent prickly heat rash
    • avoid using a pillow or mattress that your baby sinks down into
    • put your baby to bed in just a nappy.
  • Avoid taking your baby or young child outside in extreme temperatures. If you must travel, take care in the car during hot weather.
    • Never cover a baby capsule in a car with a rug or towel to shade from the sun as this will restrict air moving around the baby, which will make them hotter.
    • Use sunshades on windows.
    • Never leave babies or young children alone in a car, no matter what the weather (even in mild weather cars quickly become too hot for small children).
    • Try to make trips in the coolest part of the day.
  • If you use a fan, don’t point it towards the baby, but use it to keep the air circulating. If you have an air-conditioner, make sure the room does not get too cold (about 24 to 26 degrees Celsius is low enough).
  • If you do not have a fan or air conditioner, you can cover your baby’s or toddler’s body with cool damp cloths. You can also place wet towels or sheets around the bassinette or cot to cool the air near them. Check on your baby regularly to make sure they are not getting too cold.

Sick babies and children need special care in hot weather

Even with minor illnesses, such as colds or gastroenteritis, babies and small children need special care in hot weather. These illnesses often lead to a slight rise in temperature by themselves, but in hot weather this could lead to dehydration.

Frequent breastfeeding and extra drinks are important if your baby is ill. To cool a baby’s or a child’s hot body, try frequent lukewarm baths – NEVER cold - or sponge your baby or child down with a cool face washer. Seek help if there is no improvement or if you are worried.

Tips for all Victorians to stay safe during the extreme heat

  • Drink plenty of water, even if you do not feel thirsty (if your doctor normally limits your fluids, check how much to drink during hot weather). Eat smaller meals more often and eat cold meals such as salads. Make sure food that needs refrigeration is properly stored.
  • Keep yourself cool by using wet towels on your arms or neck, putting your feet in cool water, and taking cool (not cold) showers. Block out the sun during the day by closing curtains and blinds. Open windows when there is a cool breeze. Avoid strenuous activity like sport, home improvements and gardening.
  • Stay out of the sun during the hottest part of the day. If you must go out, stay in the shade and take plenty of water with you. Wear a hat and light-coloured, loose-fitting clothing. Spend as much time as possible in cool or air-conditioned buildings (for example, shopping centres, libraries, cinemas, or community centres).
