Not really a poem, and I think there are lots of versions, but this is the one I know best:
# If you get it out, put it up.
# If you sleep on it, make it up.
# If you wear it, hang it up.
# If you drop it, pick it up.
# If you dirty it, wash it.
# If you open it, close it.
# If you turn it on, turn it off.
# If it rings, answer it.
# If it howls, feed it.
# If it cries, love it.
I particularly like that version because of that last one - it's so in the spirit of Mothering!
