If the child has moles and freckles, then they need even higher sunscreen. If the family has a history of cancer or moles, they need to have a higher level. Sunscreen needs to be re-applied at least every two hours, or after the child has been wet, or a lot of perspiration. If you can put your hand underneath the clothing and see your hand, then probably the sun can get through. You need to wear tight woven clothes, and clothes with darker colors.
Hats are very important.
Rest time out of the sun is important. And so many times we put sun block on the kids when we go to the beach or pool, but it's playing in the back yard, or walking up the block that's important as well. Sun glasses are important for children. The cornea actually can be burned by the sun, even just in one day. Sometimes it's hard to get children to keep those sunglasses on, but it's important.
