After reading up on H1N1 the things that seem to be key are garlic, garlic, garlic, vitamin D, vitamin C, and good sleep.
Personally, I am very much not a fan of tylenol because it can cause liver damage. Has your LO recieved the vaccine? If so, Tylenol has been suspected of weakening the vaccine. (I'm not one for vaccines
Rub crushed garlic on your LO's feet, if you are still nursing eat *lots* of raw garlic (I crush it and then take it like a pill), supplement your diet with extra vit D (around 5,000IU's/day only while sick) and put LO in direct sunlight for at least 15 minutes/per day for vit D, up your vit C intake naturally with grapefruits, lemons, & oranges and you can also take extra vit C in the form of powdered sodium ascorbate- can be giving to LO in *very* small amounts in water or BM (too much can cause diarrhea), & good sleep.
Please look up cytokine storm response and make yourself aware of which foods *may* cause it (it is still not fully understood) and which foods help to reduce it.
Personally, I believe diet is the key with the H1N1. The supposed "healthy" people dying from it do not have a good diet, they all eat SAD and once you think it is gone do not stop what you are doing to get rid of it. A reoccurance of it is what is usually lethal or if it goes into the lungs ending in pneumonia or bronchitis.
Also, keep in mind a fever is there to kill the virus. Of course it it gets too high it can cause serious damage but if your LO is not bothered by it it probably isn't high enough to worry. It's when they are lethargic and delirious you need to worry.
The only reason why H1N1 is being hyped is because it is a new strain, kind of, and most people have not been exposed to it giving them natural ammunity to it. As a side note... If you are over 50yo chances are you will not get H1N1 because of the 1918 flu outbreak exposure but, there are a lot of us who aren't over 50 so there will be alot of cases of H1N1.
HTH and healing thoughts for your LO
