Can babies wear sunscreen?

Babies' skin burns quickly, and sunburns early in life raise the risk of skin cancer later. For babies under 6 months, rely on shade and lightweight clothing; the AAP says a small amount of sunscreen is acceptable on exposed areas such as the face and backs of hands when shade isn't possible. After 6 months, use broad-spectrum sunscreen with SPF 15 or higher, reapplied every two hours and after water, plus a hat, sunglasses and shade.

Key takeaways

• Midday sun, about 10 a.m. to 4 p.m., is strongest.
• Sunburn can happen on cloudy days and through water.
• Mineral sunscreens with zinc oxide or titanium dioxide are gentle on young skin.
• Overheating is a risk as well as burning.

Under 6 months

• Keep them in the shade of a tree, umbrella or stroller canopy.
• Dress in lightweight long sleeves and pants.
• A wide-brimmed hat that shades the face, ears and neck.
• Don't drape a blanket over the stroller; it traps heat.
• Small amounts of sunscreen on exposed skin if shade is limited.

Over 6 months

• Apply sunscreen 15 to 30 minutes before going out.
• Use about an ounce for an adult; proportionally less for a baby, covering all exposed skin.
• Don't forget ears, nose, tops of feet and the back of the neck.
• Reapply every two hours and after swimming or sweating.
• Use sunglasses with UV protection if your baby tolerates them.

Choosing sunscreen

• Broad-spectrum (blocks UVA and UVB).
• SPF 15 at minimum; SPF 30 is a common recommendation.
• Water-resistant for swimming.
• Fragrance-free for sensitive skin.
• Test on a small patch of skin first.

Sticks are easier on wiggly faces. Sprays can be inhaled, so spray into your hands first.

Clothing

Tightly woven fabrics block more sun. Some clothes are labeled with a UPF rating; UPF 50 blocks about 98% of UV rays. Rash guards are useful at the beach or pool.

Water, sand and snow

These reflect sunlight and increase exposure. Be extra careful at the beach, pool and in snowy mountains.

Heat and hydration

Babies can't regulate body temperature as well as adults. Signs of overheating:

• Flushed, hot skin.
• Fussiness or unusual sleepiness.
• Fewer wet diapers.
• Rapid breathing.

Move to a cooler place, remove layers and offer breast milk or formula. Babies over 6 months can have small sips of water.

Sunburn

Signs include red, warm, tender skin. For babies under 1, call your pediatrician for any sunburn. Cool compresses help; seek care for blisters, fever, chills or lethargy.

Vitamin D

Avoiding sun doesn't mean missing vitamin D. Breastfed babies usually need a vitamin D supplement; ask your pediatrician.

Car windows

Side windows block less UVA than windshields. Window shades help on long drives.

Planning outdoor time

• Check the UV index on a weather app; 3 or higher means protection is needed.
• Plan walks for early morning or late afternoon.
• Use the shadow rule: if your shadow is shorter than you, the sun is strong.
• Bring a portable shade tent to parks and beaches.

Sunscreen reactions

Some babies get a rash from chemical sunscreen ingredients or fragrances. Choose a mineral formula, test a small spot on the inner arm, and stop if redness appears.

Eye protection

Sunglasses labeled 100% UV protection, with a soft strap, help protect developing eyes. A brimmed hat adds shade.

Heat rash

Tiny red bumps on the neck, chest or diaper area often appear when babies are overdressed in hot weather. Cool the skin, dress your baby in loose cotton and the rash usually fades within days.

Common questions

Is spray sunscreen safe? Avoid spraying near faces.

Do babies with darker skin need sunscreen? Yes. All skin can burn and be damaged.

Shade that actually protects

Umbrellas and stroller canopies block direct sun, but sand, water and concrete reflect UV rays underneath. Combine shade with a hat and light clothing. Pop-up tents with UPF fabric give older babies a play area at the beach.

Checking the UV index

Many weather apps show the daily UV index. At 3 or higher, plan shade, hats and sunscreen for babies over 6 months, even on cloudy days.
