You only need 1 bottle it probably will last for a year. Read the information on Jim Humble's site and download the first part of the book, it is free.
Yes it can be used for children too, but you really should read up on it, it goes by weight. The best thing to do is to download the 2nd part of the book too, but there is fee for that.
Johny Apple Bomb has posted some information of the 2nd part so you could check his posts.
In case you don't know how, click on one of his posts and in the bottom part it will say all his messages on this forum.
There are a few answers also on the FAQ at top of page. Also check the R's.
In Adam Abrahams new DVD (all about Miracle-Mineral-Supplement ), he interviews a Dr. John Humiston, who talks about giving it to his two year-old, with great success. Just follow the 1 drop per 25 pounds ratio (unactivated Miracle-Mineral-Supplement ) Also on Jim Humble's website, there is a link to a YouTube video of MMS being administed to young children with malaria. I would have no qualms about giving it to a young child (as long as they are old enough to speak to give feedback about how they are feeling).. we have been taking MMS now for about 8 months, and are on a maintenance dose of 8-10 drops a few times a week
