A couple of good points:
1) tell your kids what are the inappropriate behaviors at an early age, so
your kids will tell you when there are some pre-signs to prevent the bad
things happening.
2) have conversation with your kid. not like
-"how is the training? "
-"it was fine"
- "good"
it is not a conversation.
3) when you suspect something bad happening, report it. let police or
relating authority investigate.
