When my grandkids start showing signs of getting sick the first thing I do is up the vitamin C.. With winter months coming up, I will be getting a few boxes of Emergen-C.. One envelope of that a day will provide them with 1000 mgs of C... Grandson use to drink it as is, but because the other kids said it was yucky, he wont drink it unless I mix it in some juice. I will also be buying ear candles and cajeput oil (sister to tea tree oil from what i have been told.... Our routine is to do the ear candle, and then put a couple of drops of hydrogen peroxide in the ears and let it bubble for a few minutes..then let the ear drain as I repeat the process on the other ear.. I then rub the cajeput oil on the skin right below the ear... cajeput is an antibacterial oil, just like the oil of oregeno...it all seems to work, we seldom get sick over here anymore and if we do, its very minor.. I know alot of folks say that the ear candles dont work, but we have had nothing but success.
I wonder if you rub the oil of oregano onto the bottom of his feet right before bed if that would get enough into his system. I would also have to make sure that his skin isnt too sensitive to it, and that the oregano didnt burn or hurt him... the only way I could think of getting it down him, was to mix it into his food... but not sure if he would eat it if the food taste funny to him.... Im thinking putting it onto the skin will be your best bet
