Shelter From the Storm

I'm planning a lesson about parental protection based on the conduct of Hester Prynne towards Pearl.  (She ignores, chastises and resorts to fantasy and euphemism with Pearl, but will not tell her the truth about what the scarlet letter means, though Pearl is persistent and precocious in her attempts to discern the reality of the situation.)  I'm hoping to have a discussion about parents' efforts to shelter their children from some of the harsher realities of life.

In my mind, I see a lesson that includes poetry, short fiction, memoir, film clips, song lyrics and even paintings, all touching at least tangentially on the idea of parental censorship for the good of the child.  But for the life of me, I can't think of any examples, and I have exhausted Google's brillance (I don't need any pedantic self-help guides, TYVM.)

Can anyone help?  Anyone?
