Sun Protection for Babies
Everything you need to know about sun & UV protection
Summer is here — bringing sunshine, warmth, and one important question: how do I best protect my baby from the sun and harmful UV rays?
On this page, you’ll learn why babies need extra protection, what works best, and what to keep in mind when babywearing or using a stroller — so you can avoid overheating or poor air circulation.
Sun protection?
But babies need sunlight, right?
That’s true — sunlight plays an important role in helping the body produce vitamin D, which is essential for healthy bone development. But what many people don’t realize is how little sunlight is actually needed. Just a short moment outdoors, even in indirect light, is already enough for your baby’s body to do its job — no long exposure required.
Why is sun protection so important for babies?
A baby’s skin is much thinner and more sensitive than an adult’s. Its natural protective barrier isn’t fully developed yet, making it far more vulnerable to UV rays. On top of that, babies have less melanin — the pigment that gives skin its color and helps protect against UV radiation. Early sun damage can also have long-term effects, such as premature skin aging or an increased risk of skin cancer later in life.
mamalila tip:
During the first year, your baby’s skin is particularly sensitive — making reliable sun protection all the more important.

3 ways to protect your baby from the sun
There are three reliable ways to keep your baby safe — and we’ll show you what really matters for each.
1. Avoid direct sunlight
The best protection is simple: stay out of direct sun.
- Spend peak UV hours (11 am to 4 pm) indoors if possible
- When outside, keep your baby in the shade or use a sunshade
Be aware: regular fabric doesn’t block all UV rays, even if it looks shady
mamalila Tip:
UV levels can be high even on cloudy days — your weather app usually shows the UV index.
When you’re on the go, a little shade makes all the difference. Here’s how to keep your baby protected — in the stroller or the carrier:
2. Choose the right clothing
Clothing is a great way to protect your baby — but not all fabrics are equal.
- Regular cotton clothing often only offers a sun protection factor (SPF) of 10–20 — which isn’t enough for babies.
- Dark colors protect better but can also make your baby feel warmer.
That’s why UV-protective clothing is ideal in summer. Look for the UPF rating: UPF 50+ offers protection comparable to sunscreen SPF 50.
Also important: A sun hat with a wide brim and UV protection Sunglasses with UV protection
Did you know? UV protection drops significantly when clothing gets wet — especially swimwear, which should always be certified.
3. Sunscreen
If you use sunscreen, choose one suitable for sensitive baby skin.
Keep in mind: sunscreens can contain chemical filters or ingredients that may cause irritation. Many experts recommend avoiding sunscreen entirely during the first 6 months.
Also important: not all sunscreens protect against both UVA and UVB rays — make sure yours does.
Sun protection while babywearing
When babywearing, it’s especially important to protect all exposed areas — arms, legs, and especially the head and neck.
Important:
The head support of your carrier is NOT a sunshade. It doesn’t provide sufficient UV protection and can even cause heat buildup. A proper sun hat with UPF protection is the better choice.
That light muslin cloth over your baby’s legs? It actually offers almost no UV protection — better go for a proper alternative.
If you rely on clothing: darker colors protect more, but can also trap heat.
And one more thing: That light muslin cloth over your baby’s legs? It actually offers almost no UV protection — better go for a proper alternative.
Our solution ? The UV cover
Looking for an easy, reliable solution? A UV protection cover makes things simple — no sunscreen needed, no extra layers, and super flexible.
What the mamalila sun cover offers:
- UPF 50+ protection for arms, legs, and feet
- Lightweight, breathable fabric
- Cooling effect in summer
- Sustainable and chemical-free
- Loose fit for good air circulation
- Extra sunshade for the head
- Suitable for carriers, strollers, and car seats
“What if I sweat while babywearing in summer?”
Yes — you’ll sweat more. But that actually helps regulate your baby’s temperature too. Your bodies adjust together, so you’re not overheating your baby.
A muslin cloth between you can help absorb moisture.
Mama tip:
Bring a spare outfit if you’re out longer. If your baby gets sweaty, you can change them and prevent them from getting cold afterward.
Sun protection for strollers
A sunshade or cover with UPF 50+ is the best option for stroller walks.
Make sure to:
- Attach it so air can still circulate (e.g. between handle and canopy)
- Never fully cover the stroller opening with a cloth — this blocks airflow and can cause dangerous heat buildup
The perfect companion for summer with baby
“Pleasantly surprised”
I was worried it might get too warm underneath. My baby tends to sweat a lot and refuses hats…
But it was actually super comfortable — you can really feel the cooling effect of the fabric.
I also love the generous fit — my one-year-old (size 86) still has plenty of room.

I love the sun cover! The fabric feels amazing and very light. My baby is well protected without overheating — also great for holidays!

“A must-have for babywearing”
We use the cover almost every day and absolutely love it!
Light, summery fabric, easy to use — and finally you feel safe in the sun :)
Also great: it folds up small into its own pocket.

What other moms ask
Light colors and breathable fabrics like cotton or linen are ideal in hot weather. Covering the skin also helps protect from the sun — but keep in mind: not all clothing provides strong UV protection.
For example, thin cotton trousers only offer around SPF 10. UV-protective clothing is much more reliable. A sun hat with certified UV protection is essential, and if your baby tolerates it, sunglasses are a great addition.
A baby’s skin is particularly thin and contains less melanin than adult skin. In addition, the skin’s natural ability to protect itself from harmful sun exposure (UVA and UVB radiation) is not yet fully developed. This is why the risk of long-term damage from UV radiation is especially high for babies.
By the way: not all harmful radiation causes immediate sunburn or redness. Some of it is invisible — but can still damage the skin.
The best way is to avoid direct sun exposure and protect your baby in the stroller or carrier with a sunshade. Try to spend the time of day with the highest UV levels (11 am to 4 pm) indoors as much as possible.
If you’re out and about, sun-protective clothing or a cover is the best solution for babies under one year. Alternatively, you can use sunscreen — but ideally only once your child is a bit older.
Sunscreen is either based on chemical or mineral filters. Chemical sunscreens may contain ingredients that can trigger allergies or that a baby’s skin may react sensitively to. In addition, some of these substances can be absorbed into the body.
For this reason, experts recommend not using sunscreen on babies during the first six months.
