Yes. That's how it works up here. Whenever there is a complaint about a domestic altercation when there are kids in the house, the cops call the CAS. When a child goes to a doctor about something wrong down there, the CAS are usually called. My daughter had a simple bladder infection when she was 9. The only time ever. The doctor nearly called for that, too. Big sigh of relief when he came out and congratulated me for the way my daughter reacted to him wanting to examine her. :P
He said that bladder infections were common enough, and allowed me to be in the room to talk her through the examination. He apologized for the inconvenience and told me that it was just procedure. For once a doctor made the right judgement call.
I dislike cops & social workers more bc of my own extremely brief experience with fostercare. I refused to stay in their care. I ran.
