@Home Remedy for Fever: VINEGAR SOCKS! When you have a baby or small child who has a very high fever and medication just won’t bring it down. Take a pair of white socks, soak them in apple cider vinegar or white vinegar. Put them on the childs feet and wrap the feet in a towel. Wait till socks have dried, if fever is still high, repeat. I’ve never had to do it twice, once has always done the trick. Trust me ladies this does work. Shoot I'll do this for me.
