If they are external toys and able to be sterilised, I offer them to mum. If I don't like them due to the harsh chemical smell which gives me a migraine, I throw them. But that's only happened once.
Other toys that aren't ones I really like but do get the job done, I tend to keep them in my cabinet with the rest of my lovelies. But they don't really see any action. One day, I'll throw them out.
