Have you ever read Dr Seuss's Fox in Socks? This piece reminds me of it a lot. Obviously it's about a more mature subject matter than Dr Seuss's work, yours being about hope and life and not about foxes in socks on boxes, etc., etc.
The reason i draw this comparison is because the way in which your poem is almost set as a tongue twister when read aloud (and yes, i read it aloud, i must've sounded crazy =P ). Especially the last two stanzas, which personally i think are the best.
My only slight criticism would be that it seems to end abruptly. Have you thought about adding a few extra lines to gently bring the poem to a stop? Just a thought - ignore it if you think i'm talking rubbish.
Anyways, i enjoyed getting my tongue around this poem (okay, that sounded kind of disgusting, but i'm sure you know what i meant), so thank you for sharing.
I'm in the rp section a lot, so maybe i'll see you around.
