Vaporizer ???

Jenica • Momma to be January 22, 2016 to a beautiful baby boy named Logan. Mommy and daddy can't wait to hold u and love u baby.
For my babyshower I got a Vicks Vaporizer and I don't necessarily know what it's used for. I know I really need one, (words of my mother) but I don't know what I exactly need it for. I'm a first time mom & im 18 so don't judge me for not knowing what it is!!! lol
