How to prevent child abuse… this is really a heavy subject to even talk about… well, the burden of prevention lies on the adults. Children are vulnerable, with no power to protect themselves from the more powerful adults. To start with, know that statistically, 1 in 6 boys and 1 in 4 girls had been sexually abused by the time they reach eighteen years of age. Just from that alone, it is likely that you know a child that is being or has been abused. By that, it is also likely that you know the abuser personally, often the unsuspecting family members (made up about 34% of the abusers). There is no way of telling them apart, appearing all nice and trustworthy. If you suspect that a child is indeed being abused, talk to the child. While you might need to make an effort to open up to the first, since they are afraid and all, it is very important to understand from the victim himself that they might be being abused unknowingly. Then keep watch of the family for a while. If you can confirm it, then report it to your local child protective service, they will know what to do from there onwards.
