Is the assessment of Nora's state of development as a child valid?I would like to know the different factors that supports this assessment and why.
A case could certainly be made that Nora's development throughout the play is like that of a child. Her interactions with her husband reflect more of a parent-child type of relationship at the beginning of the play. Torvald does out money, an "allowance", and chides her for spending swiftly-much as you would a child.
Torvald has forbidden her to eat sweets because they would ruin her teeth, and yet she sneaks macaroons when he is not around. This is another example of childish behavior. Nora keeps secrets from Torvald, such as the loan application she forged, for fear she will be punished.
She has always accepted silly little nicknames that are childish in nature, as well. She preens and sings and flits around him as a hyperactive child.
As the play progresses, and certainly at the end, she is beyond being a child. Torvald does not treat her as an equal, and by her leaving, it is as if she has grown independent of her father figure and will strike out on her own.
