As Aussie parents, we all know the dangers of the sun. But when it comes to protecting our children, the rules are a little different... especially for babies under six months.

Baby skin is thinner, more sensitive, and far more vulnerable to sun damage than adults. In fact, research shows that just a few serious sunburns in childhood can double the risk of melanoma later in life.

So, the big question many parents ask is: If my baby is too young for sunscreen, how do I keep them safe outdoors?

Let’s dive into what the experts say and explore the best sun protection options for babies under six months.

Can Babies Under 6 Months Wear Sunscreen?

The short answer: most experts recommend avoiding sunscreen under six months of age.

The Cancer Council advises against using sunscreen on newborns because:

• Their skin is thinner and more permeable, which means it can absorb chemicals more easily.
• Sunscreen can cause irritation, rashes, and discomfort.

That doesn’t mean you’re stuck indoors for half a year, it just means sun safety needs to look a little different.

Instead of relying on sunscreen, focus on shade, protective clothing (like our UV Defender Onesie), and smart timing.

Best Ways to Protect a Newborn from the Sun (Without Sunscreen)

Stick to the Shade

Wherever possible, keep your baby out of direct sunlight.

• Use a pram with a canopy or attach a breathable sunshade.
• Invest in a pop-up beach tent or portable shelter for family days by the water.

Hot tip: Make sure whatever shade you’re using still allows airflow, overheating is an even bigger risk than sunburn at this age.

Watch the Clock

UV levels are at their peak between 10am and 3pm. If you can, plan your walks, picnics, or family fishing trips for early mornings or late afternoons.

This not only keeps your baby’s skin safer but also makes the outing more comfortable in the summer heat.

Cover Up with Clothing

Clothing is your baby’s first line of defence against the sun. Look for:

• Long sleeves and long pants to protect arms and legs.
• A wide-brimmed hat that shades the face, neck, and ears.
• Breathable material to ensure your baby doesn't overheat. 

Many parents assume a rashie will do the job, but rashies only fover your baby's torso, leaving legs, hands and feet exposed. For babies under six months who can’t use sunscreen yet, full-body coverage is the safest option.

Keep Baby Cool

While covering up is essential, overheating is a genuine concern.

• Choose lightweight, breathable fabrics designed for warm climates.
• Use pram fans, misting bottles, or a dip in the shade to keep temperatures comfortable.
• Watch for signs of overheating: flushed cheeks, fussiness, rapid breathing, or damp hair.

Why Baby Skin Needs Extra Care

Newborn skin is different from adults:

• It’s thinner, which means UV rays penetrate more deeply and cause more damage
• It burns faster, in as little as 10 minutes of unprotected sun exposure.
• Babies can’t regulate their body temperature as well, making overheating a double risk when you’re covering up outdoors.
• The combination of sun sensitivity + heat sensitivity is why it’s so important to choose the right protective gear.

The Clothing Solution: Full-Body Sun Protection

While shade and timing are important, the truth is… families don’t always want to be stuck indoors. Whether it’s a camping trip, a day by the beach, or a quiet afternoon fishing, parents need peace of mind that their little one is safe.

That’s where full-body sun protective clothing makes all the difference. Unlike rashies or partial-coverage outfits:

• Arms and legs are fully covered, so you don’t need to worry about sunscreen battles.
• Lightweight and breathable designs prevent overheating, even in Aussie summers.

It’s the easiest way to know your baby is safe, even when sunscreen isn’t an option.
