Sunscreen/sunblock: The difference between is how good they are at screening out harmful radiation from the sun. Blocks are stronger and thus more effective at keeping out those harmful UV rays.

How can I convince my kids to wear sunscreen/sunblock? Any tips (anything would be appreciated, please!) ?

Just do it: Your children are not in control of their lives-you are. When you put them in a car seat and buckle them in it is to protect them from injury.

Make the decision now to do what's right for your children. Someday they'll understand the love behind the lotion. ...Read more
