You know the report process, right?
Tell the school. Tell her teachers. Tell the school counselor. Tell CPS.
IF there are two schools, tell them both. If there are three tell all three.
No Drama nonsense about that will p.o. this jackass or that one, just tell.
No Ducking nonsense about CPS will or will not do this that or the other thing, just tell.
You are only called to do the next right thing. This is it.
