Health & Safety
How do I keep my baby safe in the sun?
Why under-6-months is different
Babies under 6 months have thinner, more sensitive skin and immature ability to regulate temperature, so the NHS advice is to avoid direct sun exposure altogether at this age rather than relying on sunscreen — shade, clothing and timing are the actual protection.
From 6 months
- SPF 50, broad-spectrum, baby/child-formulated sunscreen on all exposed skin, including ears, the back of the neck and feet
- Reapply every 2 hours, and immediately after swimming or sweating, even "water-resistant" formulas
- UV-protective swimwear and a wide-brimmed or legionnaire-style hat reduce how much skin needs sunscreen at all
- Sunglasses with UV protection if your baby tolerates them
Timing and heat, not just burning
Avoid the strongest sun, typically 11am–3pm in the UK summer, for babies of any age — plan outdoor time for morning or early evening instead. Watch for overheating separately from sunburn: a hot, flushed baby needs shade and fluids even without visible burn. Never leave a baby or child alone in a car, even briefly, even with windows cracked.
