Baby in a stroller during summer – how to avoid overheating
A stroller can quickly become hot in summer, especially if it is in the sun or the opening is covered. Therefore, it is important to choose light clothing, ensure good air circulation, and check the baby regularly.
Here is a practical guide on how the baby can lie comfortably in the stroller on hot summer days.
How hot can it get inside a stroller?
The temperature inside a stroller can be higher than outside. The sun heats the canopy, mattress, and fabric, while limited air circulation makes it harder for heat to escape.
This means the stroller can feel warm even if the outside temperature seems comfortable.
The risk of the baby getting too warm increases especially when:
-
The stroller is in direct sunlight
-
The opening is covered with fabric or a blanket
-
Baby wears multiple layers of clothing
-
A thick duvet or sleeping bag is used
-
No fresh air enters the stroller
-
Baby lies for a long time without being checked
Is it okay to cover the stroller with a cloth diaper?
You should not cover the entire stroller opening with a cloth diaper, blanket, or other heavy fabric. This can reduce air circulation and cause the temperature inside the stroller to rise.
Sundhed.dk recommends not hanging heavy fabric in front of the stroller and not using plastic covers in hot weather, as it can get very hot for the baby.
Instead, use:
-
The stroller’s canopy
-
A parasol designed for strollers
-
A sunshade with good ventilation
-
Natural shade
-
A mosquito net when necessary
Always ensure that air can still move freely around the baby.
What should the baby wear in the stroller during summer?
Clothing depends on temperature, wind, sun, and how sheltered the baby is.
As a general rule, you can choose:
| Temperature | Recommended clothing |
|---|---|
| 18–22°C | Bodysuit, light pants, and possibly a thin extra layer |
| 22–25°C | Short-sleeved bodysuit or a light summer outfit |
| 25–30°C | Short-sleeved bodysuit or just a diaper, depending on conditions |
| Above 30°C | As little clothing as possible, shade, and frequent checks |
The table is for guidance only. Babies react differently to heat, and the temperature inside the stroller can be higher than outside.

How to tell if the baby is too warm?
Feel the baby’s neck, back, or chest. The skin should feel comfortably warm and dry.
Signs that the baby may be too warm include:
-
Moist or sweaty neck
-
Very warm back or chest
-
Red cheeks
-
Damp hair
-
Rapid breathing
-
Restlessness or unusual lethargy
-
Fewer wet diapers than usual
Hands and feet can feel cool even when the rest of the body has an appropriate temperature. Therefore, do not check only the child's hands.
If the baby seems lethargic, is difficult to engage with, or has breathing problems, immediately move the baby to a cool place and seek medical help.
Can a baby sleep outside in the stroller during summer?
A baby can sleep outdoors in the summer when the stroller is in the shade, there is good air circulation, and the baby is checked regularly.
Do not place the stroller in direct sunlight. Also remember that the sun moves, so a spot that is shaded at nap time may later be in the sun.
Therefore, check continuously:
-
Whether the stroller is still in the shade
-
Whether there is air circulation
-
Whether the baby's neck feels dry and comfortable
-
Whether the clothes or bedding have become too warm
-
Whether the baby is breathing normally
Should a baby have a duvet in the stroller during summer?
On hot days, a regular duvet is often unnecessary. A light bodysuit, a thin blanket, or a light summer sleeping bag may be sufficient, depending on the temperature.
Avoid combining multiple warm layers. For example, a baby usually does not need both summer clothes, a thick sleeping bag, and a duvet.
If you use a baby sleeping bag, it should be designed for the current temperature. You can read more in our guide about summer sleeping bags for warm nights and 25–35°C.
Can you use a footmuff in the summer?
A thick winter footmuff is usually too warm for summer use. A 2-in-1 footmuff with removable padding can be more flexible because it can be adjusted according to the temperature.
On milder days, the footmuff can be used without the extra padding and combined with light summer clothing. On very hot days, it is often better to skip the footmuff entirely and choose a short-sleeved bodysuit or a light layer of clothing.
Always check the baby's temperature along the way. Sun, wind, clothing, and the temperature inside the stroller are more important than the season alone.
Can the stroller be left in the sun?
The stroller should not be left in direct sunlight with the baby inside. Move it to a place with stable shade, and be aware that the shade changes position throughout the day.
If there is not enough shade, it is better to stay indoors or postpone the walk.
The canopy can provide some protection, but it does not necessarily prevent the stroller from getting hot. Good ventilation and regular checks are still necessary.
When is it too hot to take a walk with a baby?
There is no single temperature that suits all babies and situations. On very hot days, the walk should be scheduled early in the morning or later in the evening when the sun is less intense.
Avoid longer trips in the middle of the day if possible. Choose a route with shade and keep the trip shorter if the baby gets warm.
At temperatures around or above 30°C, be extra careful. A short trip in the shade may be more appropriate than a long stroller ride.
Remember fluids on hot days
Newborns and small babies need frequent meals in warm weather.
Breastfed babies may need to be offered the breast more often. Babies receiving formula should continue to have it prepared correctly according to instructions.
Contact the health visitor or doctor if you are unsure whether the baby is getting enough fluids.
Signs of possible dehydration can include fewer wet diapers, dry mouth, or unusual lethargy.
A simple checklist for hot stroller trips
Before the trip, you can check the following:
-
Is the stroller placed in the shade?
-
Can the air circulate freely?
-
Is the baby wearing light and breathable clothing?
-
Is a duvet, blanket, or sleeping bag necessary?
-
Can you easily feel the baby’s neck along the way?
-
Can you go into a cool room?
-
Do you avoid the hottest part of the day?
The most important thing is to check the baby regularly and respond if the child becomes hot, sweaty, or uncomfortable.
Frequently asked questions
How warm can it be in a stroller?
There is no fixed temperature limit that fits all situations. The stroller should feel comfortable, have good ventilation, and be in the shade. Check the baby’s neck and back regularly.
Can a baby sleep in the stroller at 25 degrees?
Yes, if the stroller is in the shade, has good ventilation, and the baby is lightly dressed. Check the baby often, as the temperature inside the stroller can be higher than outside.
Is it allowed to hang a muslin cloth over the stroller?
No, not if it closes the stroller’s opening. A muslin cloth or blanket can limit air circulation and cause the temperature to rise.
Should a baby wear a hat in the stroller in summer?
Babies usually don’t need a hat when their head is protected in the stroller on a warm day. Outdoors, a light sun hat can be used when the child is not protected by a canopy or shade.
How do you cool down a hot stroller?
Move the stroller to the shade or indoors, open for ventilation, and remove unnecessary blankets and layers. Do not put the baby back until the mattress and air in the stroller feel comfortable.
Can a fan be used by the stroller?
A fan can help with air circulation, but it must be placed safely and must not blow strongly or constantly directly on the child. It does not replace shade and regular checks.
