When ds was about 20m he started referring to his blankie as 'fwottie'. I checked many times with him, 'do you mean froggy?'but no, it is definitely fwottie. The blankie has a little elephant on it and he can say elephant so I can only conclude he's just created his own name for it. It makes me chuckle and I'd love to hear your other random toddler names for stuff.
