I am a mandated reporter. You would be surprised what things Social Services does not look into because of the laws. Filthy house beyond belief? Dishes stacked to the ceiling? Unless it means a child's health is in danger, it's lifestyle choice. Feces on the floor would be looked at.
Here are some that I have reported and no action: Hand imprint on face from slap-no.
Bite on arm by parent to child-no.
Preschooler wanders blocks from home-no
DT's children appear to be fed, go to school. I can't see what a report would be done about. Child wanders neighborhood-not reportable. Well, can be reportable, but no action. I could go on, but it doesn't matter.
