Sunscreen on Infants 101: How to Keep Your Baby Safely Protected from Day One

When the sun’s out, so are the babies—and while sunshine can be wonderful, it also brings concerns about sunburn and skin safety. As a parent, you might wonder: Is sunscreen safe for babies? and When can an infant wear sunscreen?

In this guide, we’re breaking down everything you need to know about applying sunscreen on infants, plus sun safety alternatives for the youngest ones in your care.

Why Sun Protection Matters from Day One

Baby skin is incredibly delicate. In fact, an infant’s skin is thinner and more sensitive than an adult’s, making it more vulnerable to sun damage and sunburn—even on cloudy days or during short outings.

Even a single baby sunburn can increase the risk of skin damage and long-term effects like skin cancer later in life. That’s why early sun protection isn’t just helpful—it’s essential.

When Can an Infant Wear Sunscreen?

According to the American Academy of Pediatrics (AAP), sunscreen is not recommended for babies under 6 months old, unless absolutely necessary. Instead, the focus should be on:

• Keeping babies in the shade
• Dressing them in light, protective clothing
• Using hats with wide brims
• Avoiding peak sun hours (10 a.m. to 4 p.m.)

If shade and coverage aren’t possible, a minimal amount of sunscreen on small exposed areas (like the back of hands or face) may be used as a last resort—but always consult your pediatrician first.

Best Practices for Applying Sunscreen on Infants (6+ Months)

Once your baby reaches the 6-month milestone, you can begin using sunscreen more regularly. Here’s how to apply it safely:

• Choose broad-spectrum, SPF 30 or higher
• Look for mineral-based formulas (with zinc oxide or titanium dioxide)
• Avoid products with fragrance, alcohol, or harsh chemicals
• Apply 15–30 minutes before going outside
• Reapply every 2 hours, or after swimming or sweating

Be especially careful around the eyes and avoid broken or irritated skin.

If you’re searching for sunscreen for infants under 6 months, look specifically for pediatrician-recommended products designed for ultra-sensitive skin—but again, only use them in special cases. While sunscreen helps protect your baby during outdoor play, creating safe outdoor spaces like toddler playhouses also promotes fun, shaded playtime.

Newborn Sunscreen Alternatives: Shade, Clothing, and Timing

For babies under 6 months, the safest sunscreen is not using sunscreen at all—but instead focusing on physical protection.

Try these strategies:

• Use a stroller canopy or sunshade when out and about
• Dress your baby in long sleeves, pants, and breathable fabrics
• Opt for UPF-rated clothing that offers built-in sun protection
• Limit outdoor exposure to early morning or late afternoon hours

These methods are especially helpful if you’re dealing with infant sunburn prevention during the summer or on vacation.

Signs of Infant Sunburn and What to Do

Despite best efforts, sunburns can still happen. Here’s how to recognize infant sunburn symptoms:

• Red, warm, or tender skin
• Fussiness or discomfort
• Mild swelling
• In severe cases, blisters or fever

If you suspect your baby has a sunburn:

• Move them out of the sun immediately
• Apply a cool, damp cloth to affected areas
• Offer extra breastmilk or formula to prevent dehydration
• Avoid lotions or products unless directed by your pediatrician

Seek medical advice if the burn is widespread, blistered, or causing fever. When enjoying outdoor water activities, be mindful of sunburn. Learn which swimsuit colors are best for your child to help increase visibility and safety while playing outside.
