Beautiful, descriptive language... evokes memories of reading the same story as a small child.  I love the first three stanzas; they flow wonderfully and convey the emotion I think you are trying to convey -- a sense of deep abandonment.  (At least that's the feeling I had.)  However, one decision I would make if this piece were mine: I would cut the last stanza, or rework it.  I think you have said enough in the first part of the poem, and to leave the reader hanging after "how sharp" would be intriguing.  However, that is your personal choice, and I respect it; this piece was wonderful as is.  Keep writing!

You have put into words the way so many people, myself included, feel about this story. An interesting approach to describing the painful transition from childhood to adulthood. I think the last stanza works, simply because it helps the reader understand the previous stanza. Nice!

I really loved this poem. It is truly touching. I remember at the tender age of five or seven when I first read The Velveteen Rabbit. I thought it was nice. Reading it later, I cried. Your poem touched my heart, just like the book. Brilliantly composed.
