Invest in bathing suits with swim shirts for boys and girls alike. Or have your child wear a shirt over his or her bathing suit. Have your child wear as much clothes as possible without getting overheated. Hats are also a must. Generally opt for hats that have a bill or visor to cover the face. Sunglasses are also an essential accessory year-round to protect those little eyes. Get your child a pair of glasses that will block 99 to 100 percent of ultraviolet rays. Put them on a pair of Croakies to keep them from getting lost. If you're going to be outside for an extended period of time, put up an umbrella or tent to keep children out of direct sunlight.
