You can't exactly throw them in a pot of boiling water (can you...?) or pop them in a sterilation bag. I've been washing the pacifier part with soap and hot water - which generally ends with a wet stuffed animal. I am occasionally tossing mine in the washer/dryer but I doubt that is sterilizing it. Since there seem to be several mamas that use them - how are you getting yours clean?
Re: How do you clean your Wubbanub?
If you are really wanting it truly sanitized, you could use Star-San. DH uses it for sanitizing his beer-brewing stuff, it's food-safe sanitizer.
@scarlet3egonias and @Carebella We also have something very similar to a wubbie that is detachable. It is supposed to be universal for any paci. My mom found it at a boutique this summer while on vacation. Ours is a hippo but she also bought a turtle for my brother and sil. I don't know the name of it. We just laid down for a nap so I'll post the name and try to attach a pic after nap.
