Sunburns Happen: What to Do If Your Baby Gets One

Even with the best intentions — shade, UPF clothing, hats, timing — sunburns can still happen. Babies have thinner, more delicate skin, which means even short periods of unexpected sun exposure can lead to redness or irritation.

If your baby does get a sunburn, acting quickly can help soothe their skin and keep them comfortable. Here’s a simple, parent-friendly guide to what to do next.

1. Move Out of the Sun Immediately

Take your baby indoors or into full shade right away to prevent any additional UV exposure. Their skin is already irritated and needs a break from the sun.

2. Cool the Skin Gently

Use lukewarm baths or a cool, damp cloth on the affected areas.

Avoid:

• Ice

• Very cold water

• Harsh rubbing

These can increase discomfort or irritate the skin further.

3. Keep Them Hydrated

Sunburn pulls fluid toward the skin’s surface. To support hydration:

• Offer extra breastmilk or formula

• If your baby is over 6 months, offer small sips of water

Hydration helps the skin recover more comfortably.

4. Moisturize Carefully

Use a gentle, fragrance-free lotion or pure aloe vera to help keep skin hydrated.

Avoid petroleum-based products (like Vaseline) — they can trap heat in the skin and make the burn feel worse.

5. Watch for Serious Symptoms

If your baby has any of the following, call your doctor right away:

• Blistering

• Fever

• Chills

• Vomiting

• Extreme fussiness

• Sunburn covering a large area

Babies are much more sensitive to overheating and dehydration, so it’s always okay to reach out to your pediatrician if you’re unsure.

6. Prevent Future Burns With Smart Sun Protection

The best treatment is prevention — especially for babies and toddlers.

Reliable protection comes from:

• UPF 50 clothing

• Shade

• Hats with neck + face coverage

• Outdoor time in the morning or late afternoon

• Sunscreen for babies over 6 months (on exposed areas only)

Daywear that’s breathable, lightweight, and protective makes all the difference.
