Hmm we do 10ml for the kids every 4 hours. I got that from Hylands and just follow it. Seems to be helping a lot more than just giving them cough meds and waiting for them to get better.
My kids who would get a cold and it would go right to their lungs and cough for a few weeks don't get than any more. Then end up better in a few days and no cough. It seems to just stop it in its tracks.
