Yes it definitely works.Put vicks on your childs nose , chest and feet – cover the feet with socks.Steam and humidifer in addition helps too with the cold

Not sure about feet, but I know on the chest is good. My old school aunt used to always say about wearing socks in the colder weather so I would say if you are doing on the feet, I would have socks on as well.

I don’t know if it works but yes you put it on and then socks over the top.
