I think they are being quite conservative actually - but supplement makers typically list low maintenance/preventive type doses instead of therapeutic short term doses. I note that adults can take 4 or more OUNCES a day over the short term to get rid of infections. I really cannot tell you to exceed what a manufacturer says, but if it were my infant I would give him/her a teaspoon or two several times a day up to perhaps a total of a half ounce or so for the entire day.
