My kids have been enjoying Zevia sodas for awhile.  Sometimes finding other beverages besides water & milk can be challenging.  JoJo really loves one of the newest flavors, Dr. Zevia (7g) The  kids don't bolus when they drink Zevia , it doesn't seem to affect their blood sugar and has zero net carbs.

This blurb from their website best describes Dr. Zevia:

Zevia Dr.Zevia

Just what the doctor ordered ... all natural, zero calories, with the perfect blend of natural ingredients including real cherry essence, cola nut extract and a delicious infusion of nutmeg, clove, and natural spices. The taste of Dr. Zevia might remind you of that "other doctor" you once loved. Dr. Zevia is naturally caffeinated (caffeine from coffee) and naturally sweetened with stevia.

Ingredients Include:

- Stevia
- Erythritol
- Natural Caramel
- Citric Acid
- Kola Nut Extract
- Natural Tartaric Acid
- Natural Caffeine
- Natural Fumaric Acid

Here's some more information about Zevia from their website:

Based in Seattle, Washington, Zevia LLC is the creator of the world's first all natural zero calorie soda: Zevia Natural Diet Soda.

Zevia is branded Nature's Answer To Diet Soda for one reason: the ingredients. Zevia contains none of the chemically processed artificial sugar substitutes found in other diet sodas because Zevia is sweetened with stevia. Other diet sodas also contain artificial flavors and colors. Zevia does not.

Other Zevia Flavors  -  Cola with or without caffeine , Orange, Cream Soda, Lemon Lime Twist , Ginger Root Beer ,  Black Cherry ,  Ginger Ale, Grape, Grapefruit Citrus, and Mountain Zevia.
