I was hit as a child on the face and head a lot and I have to be honest, it's not really had any lasting effect on me.

My opinion on the subject, as a last resort a clip round the ear is fine. But it shouldn't be done as a constant thing. It should be a rare occurrence.

I find it odd parents who spank their child on the bottom. If a man went and smacked a woman on the bottom it would be sexual assault whether that's the intention or not, so how is this any different? To me that's more disturbing then smacking a child in the face.
