Baby in a stroller during summer – how to avoid overheating

A stroller can quickly get hot in summer, especially if it’s in the sun or the opening is covered. That’s why it’s important to choose lightweight clothing, ensure good air circulation, and check your baby regularly.
Here’s a practical guide to helping your baby 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 the temperature outside. The sun heats the canopy, mattress, and fabric, while limited air circulation makes it harder for the heat to escape.
This means the stroller can feel warm even when the temperature outside seems comfortable.
The risk of your baby getting too hot increases especially when:
-
The stroller is in direct sunlight
-
The opening is covered with fabric or a blanket
-
Your baby is wearing several layers
-
A thick duvet or sleeping bag is used
-
Fresh air cannot get into the stroller
-
Your baby lies for a long time without being checked
Can you cover the stroller with a muslin cloth?
You shouldn’t cover the entire stroller opening with a muslin cloth, 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 this can make it very hot for your baby.
Use these instead:
-
The stroller canopy
-
A parasol designed for strollers
-
A sunshade with good ventilation
-
Natural shade
-
A mosquito net, when needed
Always make sure air can still circulate freely around your baby.
What should your baby wear in the stroller in summer?
Clothing depends on the temperature, wind, sun, and how sheltered your baby is.
As a general rule, you can choose:
| Temperature | Suggested clothing |
|---|---|
| 18–22°C | Bodysuit, lightweight pants, and possibly a thin extra layer |
| 22–25°C | Short-sleeved bodysuit or a lightweight summer outfit |
| 25–30°C | Short-sleeved bodysuit or just a diaper, depending on the conditions |
| Over 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 may be higher than outside.

How can you tell if your baby is too hot?
Feel your baby’s neck, back, or chest. The skin should feel comfortably warm and dry.
Signs that your baby may be too hot include:
-
Damp 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 is at a comfortable temperature. So don’t check only your baby’s hands.
If the baby seems lethargic, is difficult to rouse, or has trouble breathing, move them to a cool place immediately and seek medical attention.
Can a baby sleep outdoors in a stroller in summer?
A baby can sleep outdoors in summer if 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 in the shade at bedtime may later be in the sun.
So check regularly:
-
Whether the stroller is still in the shade
-
Whether there is air circulation
-
Whether the baby's neck feels dry and comfortable
-
Whether the clothing or bedding has become too warm
-
Whether the baby is breathing normally
Should a baby have a duvet in the stroller in summer?
On warm days, a regular duvet is often unnecessary. A light bodysuit, a thin blanket, or a lightweight summer sleeping bag may be enough, depending on the temperature.
Avoid combining several warm layers. For example, a baby normally does not need summer clothes, a thick sleeping bag, and a duvet all at once.
If you use a baby sleeping bag, it should be suitable for the current temperature. You can read more in our guide to summer sleeping bags for warm nights and 25–35°C.
Can you use a footmuff in summer?
A thick winter footmuff is usually too warm for summer use. A 2-in-1 footmuff with removable padding can be more versatile because it can be adjusted to the temperature.
On milder days, the footmuff can be used without the extra padding and paired with light summer clothes. On very hot days, it is often better to skip the footmuff altogether and choose a short-sleeved bodysuit or a light layer of clothing.
Always check your baby's temperature along the way. Sun, wind, clothing, and the temperature inside the stroller matter more 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 steady shade, and keep in mind that the shade changes position throughout the day.
If there is not enough shade, it is better to go 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 baby for a walk?
There is no single specific temperature that is right for all babies and situations. On very hot days, plan the walk for early morning or later in the evening, when the sun is less intense.
If possible, avoid longer walks in the middle of the day. Choose a route with shade, and keep the walk shorter if the baby gets warm.
At temperatures around or above 30°C, take extra care. A short walk in the shade may be more suitable than a long stroller trip.
Remember fluids on hot days
Newborns and young babies need frequent feeds in hot weather.
Babies who are breastfed may need to be offered the breast more often. Babies who are fed formula should continue to have it prepared correctly according to the instructions.
Contact your health visitor or doctor if you’re unsure whether the baby is getting enough fluids.
Signs of possible dehydration can include fewer wet diapers, a dry mouth, or unusual lethargy.
A simple checklist for warm-weather stroller trips
Before heading out, check the following:
-
Is the stroller in the shade?
-
Can air circulate freely?
-
Is the baby wearing light, breathable clothing?
-
Are a duvet, blanket, or sleeping bag necessary?
-
Can you easily feel the baby’s neck along the way?
-
Can you go inside to a cool room?
-
Are you avoiding the hottest part of the day?
The most important thing is to check on the baby regularly and respond if they become hot, damp, or uncomfortable.
Frequently asked questions
How warm can it be in a stroller?
There is no single fixed temperature limit that applies to every situation. 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 a stroller at 25 degrees?
Yes, if the stroller is in the shade, has good ventilation, and the baby is wearing light clothing. Check on the baby often, as the temperature inside the stroller can be higher than outside.
Can you hang a muslin cloth over the stroller?
No, not in a way that covers the stroller opening. A muslin cloth or blanket can restrict air circulation and cause the temperature to rise.
Should a baby wear a hat in the stroller in summer?
Babies don’t usually need a hat when their head is protected in the stroller on a warm day. Outdoors, you can use a lightweight sun hat when the baby isn’t protected by the canopy or shade.
How do you cool down a hot stroller?
Move the stroller into the shade or indoors, open the vents, and remove unnecessary blankets and layers. Don’t put the baby back in until the mattress and air in the stroller feel comfortable.
Can you use a fan by the stroller?
A fan can help circulate the air, but it must be placed safely and must not blow strongly or constantly directly at the baby. It does not replace shade and regular checks.
