Make-your-own oral rehydration solution! (i.e. pedia-lyte)
When Charlie was diagnosed with rotavirus, mom and dad did what any budget-conscious, net-savvy family would do: they Googled homemade Pedialyte. And they discovered that you can make your own with one teaspoon of salt, eight teaspoons of sugar, and one liter of drinkable water.
Naturally, that tastes terrible. Charlie wouldn't drink it. But his smart papa deconstructed Gerber's Liquilytes, added three teaspoons of Splenda and a packet of unsweetened fruit punch Kool-aid, and voila! quaffable homemade oral rehydration solution.
