One bad sunburn during childhood, could double the risk for skin cancer in adulthood. Doctor Todd Husty explains the best way to protect a child's new, soft skin from sunburn.

Dr. Julie Winfield/Pediatric Dermatologist: "It just hurt me so bad to see a child come in with sunburning, with freckling, with blisters when most of that, if not all of that, could be prevented if people were just a little bit more careful."

Dr. Julie Winfield is a Minneapolis pediatric dermatologist who preaches sunburn prevention.

"80 percent of our sun exposure occurs before the age of 18, and one bad blistering sunburn in childhood will increase their risk of skin cancer double. It will double it. So that if we can teach our children at a young age to be sun smart that will help prevent sun damage later on in life."

At a recent summer camp in Australia, she saw kids use sunscreen and take sunburn prevention seriously.

"In Australia, it was very exciting to see the hats are part of their uniform. They have to wear them every day, and if they don't they can't participate in outside sports."

Being careful about sun exposure, whether it's wearing a hat, wearing long sleeves or wearing sunscreen is like any other healthy habit. You have to begin in childhood and practice your entire life.

The American Academy of Dermatology recommends that all children protect their skin from the sun year round. They also recommend the use of sunscreen with an SPF of at least 15. But if your child is fair-skinned, has freckles or spends a lot of time in the sun, use an SPF of 30 or higher.

Dr. Roger Ceilley, President of the American Academy of Dermatology, says the rules for babies are much more stringent.

"For infants from birth up to six months, we recommend that you keep them out of the direct sun, in carriages or bonnets, things like that. I think at six months on, start using sunscreens. There are nice sunscreens now that are designed that don't sting."

"If we can teach our children at a young age to be sun smart, that will help prevent sun damage later on in life."

Children should wear hats during sports, to limit sun exposure. And with early detection and treatment, nearly all skin cancers are curable.
