You mentioned using lavender clorox in the bath water to help with the "fungus body smell", how much are you using to a tub full?
My daughter suffers from the same "smells" and just when i thought i had tried everything i see that i haven't. Also, how often do you bath with the clorox?
As for the cocoa butter, my dughter who is 13 likes it better than vaseline as well. It doesn't give her that globby feeling on her skin but has the same effect.
Psalms 41:3 (NIV)
The Lord will sustain [him] on his sickbed and restore him from his bed of illness.
Be blessed and Forever faithful
