The woman person in my house insists on being called "mummy", although why she would want to be called something that clearly means "boob" is beyond me. She really is most insistent on the point, resisting all my attempts to explain that her real name is "dada". I have been very consistent on this point, repeating the word Dada loudly every time that she tries to say that she is in fact called Mummy... Should I be concerned at her recalcitrance? - after all she is 37 years old - I fear she may be backward. (On other points she appears to be progressing - she now understands that "GUMMY" shouted very loudly with pointing means "give me that AT ONCE".)
