@Bluesky1234,
You didn't specify the exact conversation you had with your clinician. But it scared that person enough to escalate the situation to an outside party, CPS. You even argued with the person's supervisor, who also felt your situation needs escalated.
We don't know what prompted you to seek help in the first place. I would have to imagine it's pretty bad if you were brave enough to seek someone out about it. This isn't normal, you recognized it and took steps to fix it. For that, you are to be commended.
What may be what you thought would to be sent home with some pamphlets of smiling kids and parents playing in the back yard has now turned into an investigation of possible child abuse. That's pretty scary. A real eye opener.
Now it seems you're backtracking. You come to the defense of your husband saying he isn't all THAT bad, and besides, he's getting counselling. What you are NOT saying, is what help are you getting your children to help them through this.
CPS usually calls you and makes an appointment for an office visit interview to ascertain some information. After that, they may find it necessary to bring the children in for an interview. Those accounts from you, your husband and the children may necessitate a home visit. No, cops aren't going to come in your house. But yes, if CPS does have enough suspicion to warrant a home inspection, they have a legal right to do so. They'll check your children's school records for absenteeism and grades. Day care records if there is any. Some times they check with employers for absenteeism or any signs of physical or mental abuse signs.
CPS will ask your neighbors if they've seen or known about the yelling and how the kids seem to respond. That, you should be the most interested in, viewing your situation from a 3rd party of of view. Above all this, really see what your children are going through.
You wanted help. It's not coming in the form you expected. It's a sign that things ARE that bad and it's time to understand your children are being harmed.
Deep down you know that.
