Water is always a great bet for healthy drinking. Make sure your kid drinks plently of this daily.
If you want to treat them to something sweet, there are healthy choices as well. First of all, do not go for those sugary drinks. Stick to 100% juice such as Mott’s or Welch’s. Do not go for the juice cocktails as well. It is a good idea to dilute these a bit so they are not getting a lot of sugar, even it is derived from fruit. Fruitables is a good brand because they combine both fruit and vegetable in a great tasting combination that is a full serving of fruits and veggies. It also tastes great. If they are into veggies, then V8 is always a good bet, just don’t get the spicy one, unless they like it. Try the low-sodium kind and see if they like it as this is better for them. Even the regular one is a good source of vegetables as it is a full serving of them. Chocolate milk is always healthy too, but dilute it with 2% milk.
