I have also heard about the vapor rub on your feet. Be careful if your child has asthma or allergies though. I was using the vapor bath liquid until my doctor told me that it can actully restict the airways more if a child has asthma or bad allergies. A humidifier has worked well for us. It helps the lungs stay moisturized so the kids and adults are less suseptible to viruses and bacteria. It's not actually the cold weather that brings on the cold and flu season, but the dry stale indoor air that dries out the lungs and make us more vulnerable. Fresh air, even in the winter is healthy for the body. Just make sure you wash out the vaporizer with distilled vinager a few times a week to keep bacteria from building and getting spread through the house. Hope that helps!
