Baking soda paste really helped my boys when they came home last weekend with a nasty burn after being on the lake in a boat with my inlaws all day. Just mix it with some cool water and put it on the burn. Let it sit for 10-15 min and then get into a bath of cool water with more soda in it.
Another thing I was told when I got a nasty burn is to buy an aloe PLANT and not the gel. It works faster and they are really easy to care for. You can just put it in your kitchen window and just cut it when needed. Open it up, scoop out the gel and put it on the burn! It will work better and faster than the gel stuff you can buy at the store and you'll always have it around. It regenerates itself once cut.

(That'll teach him to put the sunscreen when I tell him to).
