The Diaper Duck has a warning, "This product is not a toy. Do not allow children to play with it." I don't have a problem with that. But if you don't want kids to treat the Diaper Duck as a toy, why did you make it toy-shaped?!
UPDATE: I should probably clarify this...the reason I ask the question is that my son has rubber ducks, and I constantly have to take away the Diaper Duck from him, because he doesn't understand the difference and wants to play with it. They just made my life a little bit harder. Might as well have made a samurai sword with a rubber duck on the handle. Or a bottle of rat poison with the Flintstones on the label.
