Even when temperatures don't reach the triple digits, it's easy for kids to end up redder than a sun-ripened tomato. Sunscreen needs to be reapplied regularly, but it's also important to ensure kids don't suffer from dehydration or sunstroke. One way to help outsmart the sun is to use Sun Signals stickers that alert you when your child has reached a high level of sun exposure and needs to reapply sunscreen, cover up with sun protective clothing or seek shade. The stickers measure UVB rays, changing from yellow to deep orange. Just stick on clothing or skin after applying sun screen and watch for the color change. Stickers come in fun shapes that kids love to wear! Look for them in the sun screen section of your favorite retailer.
