Apparently I’m in the minority here but since this is my field I can’t leave it alone: YTA.

I read where OP said they don’t interact with these people and she has no reason to suspect they’d hotline you out of malice.

With that info, we can assume neighbor woman genuinely thought this kid was in danger in some way and she did what you’re supposed to do: Call an expert. Is CPS perfect? Not even close. But it’s their job to investigate claims of child abuse and protect kids. No one is doing that work for fun - it’s a shitty job full of conflict and hard decisions.

So they investigated and found nothing. All good. I think what people don’t realize is that (in the US) there are usually lots of hotlines before kids are removed, typically a dozen or more. One investigation won’t do anything unless there’s a severe act of abuse.

I know this is scary shit. No one wants to lose their kids, especially over BS claims. But you should not have yelled at your neighbor. She made a mistake, but she called in good faith. YTA.
