AnyPro has a very cute Sparoma Aroma Diffuser thats in the shape of a baby penguin. This sweet looking diffuser is white with a metal "tip" for the beak, where the aroma comes out. It works like any essential oil diffuser and is great for the kids room Now they don't have to have a boring one.
It has a "soothing ambient light" that you can choose 3 different modes of brightness. It features an auto shut-off, so when the water is used up, it will stay safe and save energy.

This humidifier features "smart humidification technology" and can send out the cool mist for up to 10 hours. You can control the setting for a high or low mist, and can even set it on a timer for 1, 3, or 6 hours at a time, before the automatic shut off. It also has a night light you can turn on if you wanted. It's super quiet so it can even be used in the nursery.
