Swim Early, Swim Always

The earlier the better. The younger you sign your kids up for child swimming lessons, the better off they, and the better off you will be. Kids can swim at three years old. Sign them up and they'll be able to jump over their heads and swim by age four.

The longer you wait to enroll kids in swim lessons, the more afraid of the water they'll become and the larger they will be (making it harder for them and the instructor to work together, float, and relax in the water).
