8. Reduce opportunities for predators.

"Who's watching the kids?"

Take steps to eliminate or drastically reduce the number of isolated, one-on-one interactions a kid has with older people.

• make sure any isolated interactions with kids can be observed
• observe isolated interactions often & inform the adult you observed after the fact
• make sure any isolated interactions with kids can be interrupted No room with a kid in it is off limits to the caregiver/teacher/parent.
• interrupt isolated interactions unannounced, often, & at random Ex.: Come home earlier than you told the babysitter you would.  
• understand that predators often "groom" the family as well as their intended victim.  Just because you trust someone does NOT mean you should leave them alone with a child.  Even family members. 
• monitor kids' internet use
