Corporal punishment 

Parent-Educator Source, Conflict and Solution

In some cultures, spanking, smacking or hitting with a utensil or hand are still acceptable forms of behaviour management. All European countries now banned this in settings and fifty-five countries around the world ban it completely. Educators may come into contact with parents who use this sort of punishment at home or who suggest you use it with their child.  

Parents must be educated about the legal status of corporal punishment in your country.

Try to provide other options to the parent with questions:

“Would you like to hear about some other things that will work?” is a good starting point.
