Protecting your baby from extreme heat and cold
Babies can’t regulate their temperature the same way an adult does. Your baby needs to be protected from extreme heat and cold. A healthy baby can go outside every day in any season, as long as the temperature seems reasonable and they are appropriately dressed.
Cold weather
When it’s very cold, don’t stay outside too long, as your baby runs the risk of frostbite, especially if they aren’t moving around. It’s important to dress your baby warmly and ensure their head, hands, and feet are well covered.
Wind can also make your baby uncomfortable, so make sure they’re protected (by raising the stroller hood, for example).
Extreme heat
It’s true that babies need warmth. But they don’t tolerate extreme heat and must be kept out of the sun (see Protecting your baby from the sun).
If the temperature indoors is comfortable for you, it’s comfortable for your baby, too. A temperature between 20 and 22°C (68°F and 72°F) is appropriate. Indoors and out, if it’s very hot (above 25°C), short, light clothing and a diaper are sufficient. Use light blankets you can add or remove as needed.
If it’s very hot outside, avoid long outings with your baby, especially during the hottest part of the day between 11 a.m. and 3 p.m.
To check if your child is too hot, touch their neck: it shouldn’t be wet. If your baby urinates less often than usual and their pee looks darker and has a distinctive smell, they may be too hot and a little dehydrated. Remove a layer or two of clothing. Also make sure they are drinking enough (see Is your baby drinking enough milk?).
When it’s very hot, don’t put a blanket over the stroller, even if it’s to shield your baby from the sun. The temperature inside the stroller increases rapidly (see Stroller).
