Well, I got a waterless vaporizer from Vicks. They do (Vicks) have both cold and warm vaporizers also. I also found the new things you put in your shower (didn't buy them) and also some that you plug in like air freshner plug ins, didn't buy that either, but it was interesting. I didn't expect to have so many choices, lol. I also got him Little Noses, I remember using this on my oldest, it's nose drops. I actually prefer not giving him medicine, he's only 7 months so it's hard to give him alot of liquids yet. Thanks for the advice everyone, if the waterless doesn't work, I'll probably get the cold water one.
