Its ok to smack your child

From http://www.news.com.au/world/a-smacked-child-is-a-successful-child-study-finds/story-e6frfkyi-1225815802962

According to the research, children smacked up to the age of six were likely as teenagers to perform better at school and were more likely to carry out volunteer work and to want to go to university than their peers who had never been physically disciplined.

Only those children who continued to be smacked into adolescence showed clear behavioural problems.
