I think almost all of the families are having a security alarm system now. They are perfect for your safety. Have you thought about what if this system gets interrupted or we have a sudden power failure? It’s unimaginable if your child is alone at home. There is nothing to worry if we have given them proper training regarding what to do when an intrusion occurs, whom to call in an emergency etc. I felt like sharing an informative article on this. [ http://www.apialarm.com/think-safety/ ] We must make a good relation with our neighborhood. If so, even if we have to make our kids alone, we can be assured that the neighbor would have an eye on our child. Most of the children don’t know how to deal with strangers. As the crime towards children is increasing beyond a limit, we must teach them all safety measures at the early childhood itself. Hope this could help you.
