Taking your baby outside for some fresh air and sunshine is one of life’s little joys — but when it comes to newborns, sun safety becomes a serious concern. That soft, delicate skin might look adorable, but it’s also extremely sensitive to UV rays and can burn much faster than adult skin.
You’ve probably heard that babies under 6 months shouldn’t wear sunscreen, which might leave you wondering: So what should I do to protect my baby from the sun? In this article, we’ll break down exactly when sunscreen is safe for newborns, why their skin needs extra care, and what you can do to keep your little one protected outdoors.
Why Sunscreen Should Be Avoided for Babies Under 6 Months
When it comes to babies under 6 months, it’s generally best to avoid sunscreen altogether. While sunscreen is a great tool for protecting older children and adults from harmful sun rays, it’s not recommended for babies at this early stage of life.
Why? The key reason is that babies’ skin is extra sensitive and can react more easily to chemicals. Sunscreen ingredients—especially in chemical sunscreens—can be difficult for their tiny bodies to metabolize, which may increase the risk of skin irritation or even rashes.
The American Academy of Pediatrics (AAP) and the FDA both recommend keeping babies under 6 months out of direct sunlight whenever possible. Instead of Shade as Primary Protection slathering on sunscreen, it’s best to focus on alternative methods to protect your little one from the sun’s harsh rays.
The Best Sun Protection Methods for Infants
For babies under 6 months, the best protection is keeping them out of direct sunlight as much as possible. Shade is your best friend here—whether it’s from natural sources like trees or from artificial sources such as a stroller canopy or a beach umbrella. These options can help keep your baby safe without exposing their delicate skin to the sun’s harmful rays.
The sun’s rays are strongest during midday, so seeking shade is even more important when you’re outdoors between 10 a.m. and 2 p.m. This is when UV radiation is at its peak, and babies’ skin is especially vulnerable.
Clothing Protection
One of the most effective ways to protect your baby from the sun is by dressing them in sun-protective clothing. Opt for long-sleeve shirts, long pants, and a wide-brimmed hat to shield their body and face from direct sunlight. The hat should cover the neck, ears, and face—areas that can easily burn.
When choosing clothes, be sure they’re made of tight-weave fabrics, which offer better protection from UV rays. If you hold the fabric up to the light and it’s see-through, it likely won’t provide enough protection. Look for clothing specifically designed for sun protection, which often has a UPF (Ultraviolet Protection Factor) rating.
Avoiding Peak Sun Hours
We all know the sun can be hot, but did you know the time of day you’re exposed to it matters? During peak sun hours—from 10 a.m. to 2 p.m.—UV rays are at their most intense, and they can quickly damage your baby’s skin. If you can, plan outdoor activities during the early morning or late afternoon, when the sun’s rays are less harsh.
If you do need to be outside during these peak hours, make sure you have a good shade setup and your baby is dressed appropriately. Additionally, always watch for signs of sunburn or dehydration, especially during this time.
By following these sun protection tips, you can keep your baby safe and comfortable while enjoying the outdoors.
Sunscreen Use After 6 Months: What to Consider
Once your baby turns 6 months old, it’s generally safe to start using sunscreen—but it’s important to choose the right kind. At this age, your baby’s skin is stronger, and it can handle sunscreen better than it could as an infant. However, some sunscreens can still cause irritation, so it’s crucial to choose carefully.
Types of Sunscreens to Choose
When it comes to choosing sunscreen for your baby, always opt for mineral sunscreens. These types of sunscreens are made with zinc oxide or titanium dioxide, both of which form a protective barrier on the skin to block harmful UV rays. Unlike chemical sunscreens, mineral sunscreens don’t absorb into the skin, making them gentler and less likely to cause irritation.
Look for sunscreens that are broad-spectrum, meaning they protect against both UVA and UVB rays. UVA rays cause long-term skin damage like wrinkles, while UVB rays are the main cause of sunburns and are linked to skin cancer.
SPF 30+ and Reapplication
When it comes to SPF, always go for a minimum SPF 30 for babies and children. An SPF 30 sunscreen blocks about 97% of UVB rays, which is enough protection for your little one during outdoor activities.
Keep in mind that sunscreen isn’t one-and-done. You need to reapply sunscreen every 2 hours, or more often if your baby has been sweating or playing in water. Remember, no sunscreen is truly waterproof, so it’s important to apply more after swimming or excessive sweating.
Why Mineral Sunscreens Are Safer
If you’re looking for the best sunscreen for your baby, mineral sunscreens are your best bet. They sit on top of the skin and reflect harmful UV rays away, making them much less likely to cause skin irritation compared to chemical sunscreens.
Chemical sunscreens often contain ingredients like oxybenzone or avobenzone, which can cause allergic reactions in sensitive skin. Mineral sunscreens are made with natural ingredients like zinc oxide and titanium dioxide, which are generally safer for babies with delicate skin.
Signs of Overheating and Dehydration in Infants
Even with sunscreen, it’s important to keep a close eye on your baby when they’re out in the sun, especially in hot weather. Babies don’t have fully developed thermoregulatory systems, meaning they can’t regulate their body temperature as effectively as older kids or adults. Overheating and dehydration are serious risks that need your attention.
How to Identify Signs of Sunburn or Overheating
If your baby is exposed to too much sun, be on the lookout for signs of sunburn or overheating. Symptoms like redness, fussiness, or excessive crying could indicate that your baby is too hot or has been in the sun too long. Sunburns can happen quickly, even if you’ve applied sunscreen, so keep a watchful eye on your little one.
The Importance of Staying Hydrated
If your baby is outside for longer than just a few minutes, make sure they stay hydrated. Whether you’re breastfeeding or formula feeding, make sure your baby gets enough fluids to prevent dehydration. If you notice signs of dehydration, such as a dry mouth, sunken eyes, or fewer wet diapers, it’s time to get your baby into the shade and offer more fluids.
Always remember: the key to safe sun exposure is moderation. Using sunscreen, staying in the shade, dressing your baby in protective clothing, and keeping an eye on their hydration and body temperature can ensure your baby enjoys a sunny day without the risks.
How to Apply Sunscreen Safely on Babies (6 Months+)
Once your baby reaches 6 months of age, it’s generally safe to start using sunscreen — as long as you choose the right type and apply it correctly. Here’s how to do it step by step.
How Much Sunscreen Should You Use?
To make sure your baby is fully protected, use about half a shot glass (roughly 1 ounce) of sunscreen for full-body coverage. It might seem like a lot, but using too little can leave their skin exposed to harmful UV rays.
Apply sunscreen to all exposed areas, including:
-
Face and cheeks
-
Ears
-
Neck (especially the back)
-
Arms and legs
-
Tops of the hands and feet
Tip: For the face, you can use a small amount and dab it on with your fingers. Be gentle around the eyes and avoid getting any product too close.
When Should You Apply Sunscreen?
Timing matters. Sunscreen should be applied 15 to 30 minutes before you go outside. This gives it enough time to form a protective layer on your baby’s skin.
If you’re in a rush, you might be tempted to apply sunscreen on the go — but for the best protection, try to apply it at home before heading out.
How Often Should You Reapply?
Even the best sunscreen wears off over time, especially when babies are active.
Reapply sunscreen:
-
Every 2 hours
-
After sweating
-
After swimming or water play
-
After drying off with a towel
If you’re using a water-resistant formula, you might get a bit more time, but reapplying often is still the safest choice.
Bonus Tips for Safer Application
-
Patch test first: If you’re trying a new sunscreen, apply a little to a small area of skin and wait 24–48 hours to check for any reaction.
-
Choose mineral sunscreens: Formulas with zinc oxide or titanium dioxide are gentle and sit on top of the skin instead of being absorbed.
-
Distraction helps: If your baby’s squirmy, try singing a song or handing them a toy while you apply.
Year-Round Sun Safety Tips for Babies
Sun protection isn’t just a summertime thing — babies need to be protected all year round. Even when the sun doesn’t feel strong, UV rays can still cause damage to their delicate skin.
Don’t Be Fooled by Cloudy or Cool Days
Just because it’s overcast or chilly outside doesn’t mean your baby is safe from UV exposure. UV rays can still pass through clouds, and in many places, UV levels stay high throughout the year — even in winter.
So whether it’s sunny, cloudy, or breezy, sun protection should always be part of your routine when spending time outdoors.
Watch Out for Reflected UV Rays
Sun exposure isn’t just about what’s coming from above. Surfaces like sand, water, concrete, and even snow can reflect UV rays back onto your baby’s skin. That means your little one can still get sunburned even while sitting in the shade.
Whenever possible, choose shaded areas that also block reflected rays, like dense trees or full canopies — not just open umbrellas or partial cover.
Shade First, Sunscreen Second
It’s always best to encourage your baby to stay in the shade. Whether you’re at the park, beach, or on a walk, look for covered areas and use sunshades on strollers or car seats.
Remember, sunscreen should never be your only line of defense. It works best when used alongside other sun protection methods like clothing, hats, and good timing.
Signs of Sunburn or Overheating to Watch For
Even with your best efforts, sometimes the sun sneaks in. That’s why it’s important to know the warning signs of sunburn or overheating in babies — so you can act quickly and keep them safe.
What to Look Out For
If your baby’s been in the sun and you notice:
-
Red or flushed skin
-
Warm or hot skin to the touch
-
Fussiness or unusual crying
-
Lethargy or acting more sleepy than usual
-
Dry lips or fewer wet diapers (possible sign of dehydration)
They could be experiencing sunburn or overheating.
What to Do If Your Baby Gets Red or Irritated
If your baby’s skin looks red or irritated:
-
Move to a shaded or cool area immediately
-
Gently cool the skin using a cold, damp cloth
-
Keep your baby hydrated with breast milk or formula
-
Avoid further sun exposure for the rest of the day
Try not to use lotions or creams unless approved by a pediatrician — newborn skin is sensitive, and some products can make things worse.
When to Call the Pediatrician
You should contact your baby’s doctor right away if you notice:
-
Blistering on the skin
-
A fever over 100.4°F (38°C)
-
Persistent redness, swelling, or discomfort
-
Signs of dehydration, like a dry mouth or no wet diaper in 6+ hours
It’s always better to be cautious when it comes to your baby’s skin and health. If something doesn’t feel right, trust your instincts and reach out for help.
Conclusion
