The short answer: sun rules by age
Kids don't need complicated sun care — they need the right defaults for their age, applied every single time. Here's the whole plan in one table.
| Age | Sunscreen | Everything else |
|---|---|---|
| Under 6 months | Not routinely. If shade is truly impossible, pediatric guidance allows a small amount on small exposed areas like the face and the backs of the hands. | Shade first, always: stroller canopy, lightweight long sleeves, a brimmed hat. Babies this young shouldn't be in direct sun at all. |
| 6 months and up | Broad-spectrum SPF 30+ on every exposed bit of skin, reapplied every 2 hours — sooner with water play or heavy sweating. | Shade during peak UV, a hat that covers ears and neck, sunglasses if they'll keep them on. |
| Everyone | Same rules as the kids. Parents burn too, usually while applying everyone else's. | One adult owns the schedule for the whole group. That's the step everyone skips. |
Based on pediatric sun-safety guidance. Shade and clothing come first at every age — sunscreen covers whatever they don't.
Why kids burn faster than adults
A child's skin is thinner than an adult's and hasn't built up the gradual melanin conditioning that comes from years of moderate sun exposure. The same UV dose simply does more, faster.
The second problem is behavioral: adults notice the heat, the tightness, the little warning prickle, and drift toward shade. Kids notice none of it until the burn already exists. At High UV (6–7), fair skin can start burning in roughly 15–20 minutes — and in the burn model UV Buddy runs, kids' fair skin often behaves like the most sensitive adult types, Type I and Type II. Twenty minutes is one sandcastle.
It's worth getting this right now, not just for a comfortable week: major dermatology bodies link sunburns in childhood — especially blistering ones — to a higher risk of skin cancer later in life. That's not a reason to fear the outdoors; it's a reason to keep burns off the table while your kids rack up their outdoor hours.
The real failure mode: five people, three sunscreen times, zero memory
Sun protection at the pool or park rarely fails because parents don't know the rules. It fails because the rules multiply: you applied yours at home at 9:40, the toddler got done at 10:15, the eight-year-old swam at 11 and needs redoing now, somebody spent an hour in the shade, and nobody wrote any of it down. Five people, three different sunscreen times, zero memory. The fix isn't better intentions — it's per-person timers.
That's exactly what UV Buddy is built around. Every family member gets a profile — unlimited profiles — each with their own Fitzpatrick skin type, their own SPF, and their own adjustable timer length. Timers run separately and simultaneously, and reapply alarms are real iOS alarms that ring even with the app closed, mid-sandcastle. Tap “Applied” as you coat each kid, tap “In shade” during lunch so the clock reflects reality, and the family lotion plan lays out everyone's day at a glance. At the end of the month, the sunscreen report card even shows which kid keeps getting missed.
The beach-day protocol
A repeatable sequence beats a vigilant mood. This one holds up:
- Apply before leaving home. Sunscreen bonds better to clean, dry skin, and a child standing in a kitchen is a friendlier target than one sprinting across hot sand.
- Start the timers as you apply. One per person, 2 hours each — the deadline is set while your hands still smell of sunscreen, not remembered later.
- Reapply after every swim. “Water-resistant” on a label means 40 or 80 minutes in water at most, and towel-drying removes more.
- Shade for lunch, roughly 11–3. That's the peak-UV window; a burrito in the shade quietly removes the most dangerous hours from the day.
- Rash shirts beat willpower. A long-sleeve swim shirt protects the torso for the entire session with zero negotiation. Clothing marked UPF 50 blocks a consistent amount of UV all day — nothing to reapply, nothing to forget.
Do sunscreen at home, before the car. Dry skin, a still child, no wind, no sand — every part of the application gets better. The beach is where sunscreen goes to fail.
One timer per kid, one glance for you
Every family member gets a profile with their own skin type, SPF and timer length — and every timer runs at once. Alarms ring like real alarms whether the app is open or not, and the day's lotion plan shows who's due next, with “Applied” and “In shade” taps keeping the schedule honest.
Mini-FAQ
What SPF should kids use?
Broad-spectrum SPF 30–50. Mineral formulas (zinc oxide or titanium dioxide) sit on top of the skin rather than absorbing into it, so they're often gentler on sensitive young skin. Our SPF guide covers how to match the factor to skin and plans.
How often should kids reapply when swimming?
After every swim, full stop — and no later than every 2 hours regardless. Water-resistance ratings only promise 40 or 80 minutes of protection in the water, and towels take off plenty on the way out.
When can babies go in the sun?
Outside anytime; direct sun, not before 6 months. For young babies the protection plan is shade, clothing and a brimmed hat — with sunscreen used only sparingly, on small exposed areas, when shade truly isn't available.
