The beverages that parents put in the fridge matter, especially when rehydrating active youth and teens. So it's important to think about the most suitable beverages for active youth and teens before they drink.
Water is an OK beverage, especially when nothing else is available.
However, water has its limitations. It does not provide energy, which may be needed in a stop and go sport like soccer. Also, in an active situation most people, including kids, will stop drinking water before their fluid needs are met. Often this is because water lacks the taste appeal of a lightly flavored beverage. If given a choice, kids and teens will drink much more of a flavored beverage than a glass of water.
