If you just want to add a little bit of Mickey to the room, check out options using Mickey Mouse wall decals for kids or even cool Mickey Mouse decor and furniture like clocks and figurines and even a sofa. My favorite is the chair shaped like Mickey's head!
(And, no, I didn't forget Minnie Mouse. There are a few options featuring just her, including a toddler bedding set that's just adorable.)
