My pleasure! @bearbayou
Here is the recipe for my homemade rehydration solution:
1 liter of mineral water
1 level teaspoon of salt (3.5g)
2 level tablespoons of sugar (20g)
Fresh coconut water (not processed/commercial) can also be an excellent alternative if it's available in your region of the US.
Would it be interesting for your son to join our group as well?
Wishing you a nice weekend!
