i just went to walgreens and bought a 10 or 11 dollar vaporizer. i dont know what brand, but i dont think it matters......i am not sure if a humidifier and vaporizer r the same...but i used a vaporizer....
i dont know how a humidifier works, but the vaporizer blows out steam, which i really good. kind of like how someone else suggested the steam from a shower.... i tried the shower thing, but bella was so little, and even when i closed the bathroom off i still felt like she wasnt getting enough steam.....
