So sorry about this. I think you said at one time you like natural home remedies. So I wanted to offer one up.
During cold and flu season I always use saline sinus rinses. They help prevent colds, etc by washing away some of the bateria ans viruses we breathe in. And if you or your kids do get sick, they help thin the mucus which helps with congestion. I even add a couple drops of tea tree oil and iodine to help fight infection.
Before I tried them I was thinking NO! But they're easy and don't hurt at all.
Thanks for the tip! I'll have to google how to rinse your sinuses.....
