So how do you apply total water recommendations to your kid's day? As a rule of thumb, to get enough water, your child or teen should drink at least six to eight cups of water a day and eat the recommended number of servings of fruits and vegetables every day. Also, pay special attention to your child's or teen's water consumption when he or she is physically active. Before, during and after any physical activity, kids need to drink plenty of water, especially in hot weather. The goal is to drink a half cup to two cups of water every 15 to 20 minutes while exercising.
