Well, the "official" ruling is in from CPS, and our case has been closed. The investigator found no evidence of neglect on our behalf regarding the children.
While I took what many perceived to be a "hardline stance" with CPS, they made it clear that they felt we were very cooperative with the investigation. I returned all phone calls within 24 hours, and followed up with written communication. At no time, however, did I allow them to enter our home (although I did allow them to interview the children under very specific circumstances where we were allowed to observe and record the entire interview).
While it's a relief to be officially absolved of any wrongdoing, it still hurts to have even been accused of such in the first place. We desperately need a system where parents aren't held to be guilty until proven innocent.
