Treating Children
It is perfectly safe to have children and babies take MMS1. Of course, they must take fewer drops than adults.
• The formula for babies is half a drop per hour.
As always, use either 5 drops of 10% citric acid activator for each drop of MMS1, or one drop of 50% citric acid.
For children other than babies, use
one drop of MMS1 for each 25 pounds (11.4 kg) of body weight per hour as the maximum dose, but start with one drop per hour.
The protocol for children is essentially the same as for adults, but uses smaller amounts. If the child is very sick, start at half a drop or less per hour. To make a half-drop dose, make a one-drop dose and pour out half before giving it to the child. Then increase from 1 to 2 or 3 drops as directed in Protocol 1000, but:
• Do not go beyond one drop for each 25 pounds (11.4 kg) of body weight per hour.
Do not increase the dosage to more than half a drop for a baby per hour. If the baby or child becomes nauseous, make the doses smaller. Give smaller doses until the baby or child can tolerate more, but do not stop administering doses except in cases of extreme nausea or diarrhea. In those cases, wait until the diarrhea or nausea has passed before continuing with smaller doses.
Dosage For Overweight People
If you are overweight, start with 2 drops for the first dose and work up to 3 drops plus one drop for each 25 pounds of body weight over 175 pounds. Overweight people have more trouble overcoming flu and other diseases, as the pathogens hide in fat tissue. Follow the protocol guidelines and don’t make yourself nauseous by overdosing. Reduce the number of drops when you feel nausea coming on, or if you experience diarrhea or severe fatigue, then increase the number when you feel you can.
Normally, don’t go over the 3 drops plus one drop for each 25 pounds of body weight over 175 pounds."
If all else fails, read the instruction manual!
