I wanted to add that it's not that I don't believe in reporting genuine cases of neglect and abuse - I do!!!! Dear god, I hope no one is thinking that I believe abuse should go unchecked. I'm the first to cry over any news of children being hurt or abused. It's something close to my heart.
I just think claims that are unsubstantiated should go unreported only because CPS can get crazy for no reason. Lives really do get turned upside down for no good reason and it's not fair to put families through this if you're not 100% sure that there are actual issues. If I suspect abuse and I'd like to make a report, I will *ensure* abuse is actually going on, i.e. I've seen it with my own eyes or heard it with my own ears. Not what my child reports is going on. That's a start but that shouldn't be the basis of my claim.
If this little girl had come over and complained that her dad never let her eat, kept them in the dark even though they were crying scared or anything else that seemed abusive, then I'd look into it a little further by asking her more questions.. and paying her mom a visit. Children are great storytellers - What may be a non issue in general, can be something quite big to a child because they lack perspective.
P.S I know the OP didn't report anything to CPS, but rather to the school counsellor. A counsellor is a mandatory reporter though, so they're really not that far away.
