HI Vera. Calling and reporting to CPS is a common theme. After 3 such tries, CPS usually figures out what's going on. Let your daughter go through her calls and consider these speed bumps - of course, you'll need to be clear of all claims and "perfect' in your conduct and free of blame.
You're not alone. Ps love to have an audience and she's riding a high right now, but when CPS finally learns the truth, she'll come crashing down to reality.
Learn as much as yuo can as fast as you can and protect yourself financially and emotionally. Invite CPS over any time to check that what she says is false and she is projecting her pathology onto you.
