Skip the spray sunscreen for kids.
I would not use spray sunscreen directly on children.
The inhalation risk is real — not just theoretical. Kids breathe closer to the spray, have smaller airways, and are more likely to squirm or cough while you spray. Plus, spray sunscreens are notoriously easy to apply unevenly, which means patches of burnt skin and a false sense of coverage.
If you do use spray, spray it into your hands first, then rub it on. That solves both problems: no inhaling, and better application. But honestly? Lotion is just as fast when you get used to it, and you don’t have to worry about a cloud of chemicals floating into your kid’s face.
Lotion is easier to get right, and that’s the whole point.
