When temperatures climb, little ones need special attention. Their bodies do not regulate heat as well as an adult's, and they don't always know how to express their thirst or discomfort. Fortunately, a few simple habits can help protect baby from high temperatures while enjoying the summer with more peace of mind.
Why is baby more sensitive to heat?
Infants are more susceptible to dehydration and heatstroke. It is therefore essential to plan ahead: offer drinks regularly, limit outings during the hottest hours, and maintain an environment that is as cool as possible.
1. Offer drinks more often
Do not wait for baby to signal their thirst. If they are exclusively breastfed, offer the breast more frequently. If they receive infant formula or if their diet is already diversified, offer them water regularly—by bottle, cup, or glass, depending on their age.
When it is very hot, official recommendations suggest offering water at least every hour during the day, as well as during nighttime awakenings. For a baby who has started solid foods, fruits and vegetables rich in water can also complement meals. Water remains the essential drink, however: sugary drinks and juices are not necessary.
2. Keep the house cool
Close the shutters, blinds, and windows during the hottest hours, then ventilate early in the morning, in the evening, or at night when the temperature drops. Settle baby in the coolest room in the house and prioritize quiet play.
If a window is left open, never leave baby alone near it, even for a few seconds.
3. Choose a light outfit
Indoors, reduce layers of clothing: when it is very hot, a single diaper may suffice, including for sleeping. Outdoors, choose loose, light-colored, and lightweight clothing, ideally made of cotton or linen.
The goal is not to leave baby completely undressed in the sun, but to favor breathable materials while protecting their skin.
4. Go out during the coolest hours
Limit walks, especially for babies under one year old. Whenever possible, go out before 11:00 AM or after 9:00 PM and always seek shade.
In the stroller, use the visor or a parasol to create shade while allowing air to circulate around the baby.
5. Protect baby from the sun
Direct sun exposure is not recommended before the age of one. Even in the shade, provide a wide-brimmed hat, UV-filtering sunglasses, and covering but lightweight clothing. Apply appropriate, high-SPF sunscreen to areas that remain exposed.
Vigilance must be increased near the water, on sand, in the mountains, and in overseas territories, where UV rays can be particularly intense.
6. Cool baby down gently
You can offer a lukewarm bath around 34°C to 35°C (93°F–95°F), which is slightly cooler than body temperature. A mister on the face and body can also help cool them down.
Always stay within reach during a bath or swim: a baby should never be left alone in water, even for a very brief moment.
7. Adapt sleep
Set up the bed in the coolest room and remove unnecessary layers of clothing. Maintain standard safe sleep rules: baby sleeps on their back, on a firm, clear mattress, without a pillow, blanket, bumper, or soft object near their face.
8. Be extra vigilant in the car
Bring enough water for the trip and cool down the interior before putting the baby in. Never leave a child alone in a parked car, even for a few minutes and even with the windows cracked open. The temperature can rise there very quickly.
9. Recognize warning signs
Consult a doctor quickly or go to the emergency room if baby has a fever over 38°C (100.4°F), vomiting, diarrhea, or if they urinate less often and their urine becomes darker. In case of doubt or emergency, call 15 or 112.
A quick checklist before going out
- Water in sufficient quantity according to baby's age and diet;
- a wide-brimmed hat and UV-protective sunglasses;
- lightweight, loose, and covering clothing;
- appropriate sun protection;
- a mister and a parasol or stroller visor;
- an itinerary that prioritizes shade and cool places.
Enjoying summer, simply
With a little planning, summer can remain a mild and pleasant season with your baby. Regular hydration, shade, light clothing, and well-chosen outings already make a big difference.
