Here are two links to the US ALLIANCE TO END THE HITTING OF CHILDREN. This organization was one of the sponsors of the Symposium on Ending Corporal Punishment in the US at Loyola University of Chicago: http://www.luc.edu/media/lucedu/chrc/may2014symposium/Symposium%20Schedule-051414r.pdf
The Alliance is helping to bring together materials from many sources and to coordinate and share information and strategies to support the "It's NEVER ok to HIT A CHILD" message and to promote and educate about positive parenting strategies.
