Rehydrating Your Child Naturally: Homemade Pedialyte. recipe is recommended for children who are older than 1, generally healthy with properly functioning kidneys, and not experiencing severe dehydration or high fever (which would probably require direct medical attention anyhow). And, as always, follow your own doctor’s advice over anything you find on the internet! Homemade Pedialyte Recipe Mix together: 1 quart water 2 tablespoons sugar 1/2 teaspoon salt Note: If you fear your child will think this drink is too plain consider adding in a couple splashes of orange Juice. Also, the sugar and salt may dissolve more easily if you warm up the water first. I did also ask Dr. Kilbane about using coconut water for rehydration since it does contain some natural electrolytes, but the concern there is the lack of sodium. Your body needs the sodium to help you retain the liquid, otherwise it will just go right through you. You could potentially add 1/4 teaspoon salt and some OJ to coconut water to make sure both the sodium and sugar aspects are covered, but the recipe above is a sure thing.
