Thinkbaby vs Blue Lizard Kids Sunscreen: Which for Daycare? (2026)
Both are mineral SPF 50 sunscreens most daycares will accept. Compare zinc content, how each rubs in, water resistance and what your center's policy is likely to require.
Both are mineral SPF 50 sunscreens that most centers will accept, and either is a defensible choice. Pick Thinkbaby if rubbing in without a white cast matters, and Blue Lizard if you want the higher zinc concentration and the cap that changes colour in UV light. The colour-changing cap is a gimmick that turns out to be a useful one with children, because it makes an invisible risk visible.
Thinkkids Kids Sunscreen SPF 50+, Mineral Formula, Water Resistant, 6 Fl Oz
Mineral zinc oxide formula, water resistant to 80 minutes, and the easier of the two to work into skin without a heavy white finish.

Blue Lizard BABY Mineral Sunscreen with Zinc Oxide, SPF 50+, Water Resistant
Higher zinc oxide concentration, fragrance free, and a bottle cap that turns blue in UV light as a visible reminder.
Check price on AmazonSunscreen at daycare is a policy question before it is a product question. Most licensed centers require written parental permission to apply sunscreen, require the bottle to be labelled with the child's full name, and will only apply what you send. Some ask for a single bottle that stays at the center. Ask for the form before you buy, because it will tell you whether you need one bottle or two.
Both of these are mineral sunscreens, meaning zinc oxide sits on the skin and physically blocks UV rather than being absorbed. That is the category most often preferred for young children and for sensitive skin, and both of these are fragrance-light or fragrance-free formulations aimed at that use.

Choose the Thinkbaby Kids SPF 50+ if…
You want the one that goes on more easily. Thinkbaby's formulation is the lighter of the two to spread and leaves less of a white finish, which sounds cosmetic but is not: sunscreen that is unpleasant to apply gets applied thinly, and thin application is the most common reason a high SPF underperforms in practice. It is also the more widely stocked of the two.

Choose the Blue Lizard Baby SPF 50+ if…
You want a higher zinc concentration and a fragrance-free formula, or you have a child with reactive skin. The UV-sensing cap is genuinely useful with older toddlers and preschoolers, because it makes the sun's intensity something they can see. Expect a heavier white cast and expect to spend longer rubbing it in.

Age, and when to ask a doctor
The FDA and the American Academy of Pediatrics advise keeping infants under six months out of direct sun and using shade and clothing rather than sunscreen, with small amounts of sunscreen on exposed areas only when shade is not available. For any child with eczema, a known allergy or a reaction to a product, ask your pediatrician or a dermatologist rather than switching brands repeatedly. Reapply every two hours and after water play regardless of which bottle you own.

Frequently Asked Questions
Will daycare apply sunscreen for my child?+
Most licensed centers will, but almost all require signed written permission first, and most will only apply a product you supply with your child's full name on it. Some states classify sunscreen application under medication policy, which adds a form. Ask the director for the specific form at enrolment rather than on the first hot day.
Is mineral sunscreen better for children?+
Mineral filters, meaning zinc oxide and titanium dioxide, are the ones most commonly recommended for young children and sensitive skin, largely because they sit on the surface and are less likely to irritate. What matters more than the category is that a broad-spectrum SPF 30 or higher is applied generously and reapplied every two hours.
What SPF do children need?+
Broad spectrum SPF 30 or higher is the standard recommendation, so both of these exceed it. Going above SPF 50 buys very little additional protection and can encourage staying out longer, which is the opposite of the point. Shade, hats and long sleeves do more than a higher number.
Can I use sunscreen on a baby under six months?+
Guidance is to rely on shade and clothing for infants under six months and to keep them out of direct sun, using a small amount of mineral sunscreen on exposed skin such as the face and backs of hands only when shade is not possible. Your pediatrician is the right person to ask about your own baby.
