Among many poems that I’ve read with my daughter, The Raven by Edgar Allan Poe really stands out.
I haven’t read it to her as often as Prufrock, but it’s a close second.
She loves the imagery and the musicality in The Raven.
She even named a giant Ugly Doll stuffed animal ‘Lenore’.
(Nowadays, her sense of the gothic can be seen in her appreciation of Tim Burton films: she loved Coraline, the Nightmare Before Christmas, and the Corpse Bride.)
Here is Wikipedia’s entry on The Raven.
Here is the poem itself on the Poetry Foundation’s site.
