I'm a supply teacher. You may know that supply teachers can leave or be no longer required at any time. I don't write policies, but I do communicate with those who do, or who might ask me to. I will read my school's policy. I won't hold my breath until I find the helpful bit. I have read the EYFS Statutory Framework. If I adhere strictly to that I do not physically intervene with children except to prevent harm. It doesn't say anything about kissing, hugging, or placing on laps.
