It should be based upon minimum dosage and how the body responds, positive or negative, and we increase or decrease accordingly. Children in general is usually half of the adult dose. As to the weight thing, there is no clear grounds, but what I do know is people with more weight need much more alkaline forming foods and this dose is weight dependent, including the baking soda too but not absolutely since the length of the intestines is still the same, for equal height.
