Poems that are simple, lyrical, and very fun for kids - lots of opportunity for interacting and/or personalizing based on the words. For example:

Here comes a mouse
Mousie, mousie, mouse
With tiny light feet
And a soft pink nose
Tickledy tickle
Wherever he goes!

or

Phoebe in a rosebush
Phoebe in a tree
There's many a Phoebe in the world
But you're the one for me

And what child won't feel better going to sleep after hearing the verse:

All tucked in & roasty toasty
Blow me a kiss good-night
Close your eyes till morning comes
Happy dreams & sleep tight
