The kind of wife Helmer wants Nora to be is revealed in his comments towards her, and his pet name for her: his little bird, his songbird, etc. He wants her to be smaller than he is, on a psychological level. He wants her to be the largest and most impressive of the children in his house. He wants her to be pretty, and sweet, and to sing and dance for him, both literally (as she dances for him in the play) and figuratively (doing all for his approval, showing off for him). He want her to be dependant but impressive, needing him for all things, but showing off for others, to show how great a man he is.
