My DD has a yeast rash. I've switched to sposies because of the creams I'm using on it. I bleached all my inserts and sunned them to kill the yeast. I'd planned to use tea tree oil on my pockets, but now I'm finding conflicting advice on using it. Will a few drops in a full wash load cause repelling issues? Is there a better way to make sure my pockets are yeast-free?
