SPF for Little Ones: Let's Cut Through the Noise
SPF for Little Ones: Let's Cut Through the Noise
Every summer the sunscreen conversation starts up again and somehow gets more confusing every year. Mineral vs chemical, SPF 30 vs SPF 100, spray vs lotion, reef-safe vs not. We're going to make this simple.
Under 6 Months? Put the Sunscreen Down.
We know — it feels completely backwards. Baby skin is so delicate, shouldn't we be coating it in SPF 100? Actually, no. Infant skin absorbs chemicals much more readily than older skin, and their bodies aren't equipped to process those ingredients safely yet. The FDA recommends keeping sunscreen off babies under 6 months entirely.
So what do you do instead? The best sun protection for a newborn doesn't come in a bottle.
Keep them in the shade whenever possible. Dress them in lightweight, tightly-woven long-sleeve clothing and a wide-brimmed hat that covers the face, neck, and ears. Avoid peak sun hours between 10am and 4pm. Simple, effective, zero chemicals required — and honestly more reliable than anything you'd squeeze out of a tube.
For Older Kids: Not All Sunscreen Is Created Equal
Once your little one hits 6 months, sunscreen is fair game — but you're going to want to be picky about which kind.
Chemical sunscreens work by absorbing UV rays and converting them to heat. The problem is the active ingredients — oxybenzone, avobenzone, octinoxate — get absorbed into the skin and bloodstream, and research is genuinely still catching up on what that means long-term for kids. We'd rather not find out.
What you want is a mineral sunscreen — specifically one with non-nano zinc oxide or titanium dioxide. These sit on top of the skin and physically block UV rays without being absorbed. They're gentler, better tolerated by sensitive skin, and safer for kids who are going to have sunscreen on their bodies all day every day for the next several months.
Yes, they can leave a slight white cast. Your kid is going to get muddy in about four minutes anyway.
What to look for: Non-nano zinc oxide or titanium dioxide.
What to avoid: Oxybenzone, octinoxate, homosalate, and anything that sounds like a chemistry exam.
Sunscreen Is Your Second Line of Defense — Not Your First
This is the part most people skip over. Sunscreen is great, but clothing blocks UV rays more reliably than any lotion, doesn't need to be reapplied every two hours, and won't get rubbed off the second your kid hits the water. It's the more dependable option, full stop.
That's why we're particular about the swim and sun protection we carry at Lorelei's for Littles. Our hi-vis swim shirts, long-sleeve rash guards, and full-coverage swimwear are designed to keep kids covered without overheating — because a kid who is comfortable is a kid who actually keeps their sun protection on. Pair any of them with a brimmed hat and you've got solid coverage before you even crack open the sunscreen bottle.

The Short Version
Under 6 months: shade, clothing, hat. No sunscreen. 6 months and up: mineral sunscreen with zinc oxide or titanium dioxide, applied generously and reapplied every two hours or after water. Everyone: cover up first, sunscreen second, and don't stress the white cast.
That's it. You've got this.
