Help with sick babies?

My children are 3, 2, and 5 months and they have all came down with colds, my youngest has bronchitis, I took them to the doctor and got what medicines they needed but I was wondering what other parents did, along with the medicine to help sick babies, I bought the Johnsons vapor bath before I came to work so I was going to use it on my baby tomorrow, does it work well? Or do you know of any other products that work well...I hate to see my babies feeling bad :(
