I've been sharing time between Seamus Heaney's Opened Ground, Charles Baudelaire's Fleurs du Mal, and T.S. Eliot's Selected Poems.
I've been reading a bit to my kids from Jack Prelutsky's It's Raining Pigs and Noodles and a collection entitled Poetry Speaks to Children. The latter comes with a CD of the poems being read, usually by the poets themselves. The work includes some of the ageless poets like Blake and Frost and some more recent poets, like Billy Collins, X.J. Kennedy and Rita Dove.
From the poets here, I've got a few volumes that I return to regularly - folks like William Haskins, Dylan, jst5150, dobiwon, and caseyquinn. I've got LimeyDawg's book in my sights.
