I finally met C's teacher yesterday. The first week the weren't put into class groups but worked in year groups intead. Last week I focused on getting D off to Prep and picking her up, so I hadn't made it up to the year 2 classrooms.
Monday I instructed C to wait for me at her classroom but she thought I was taking too long and came to the Prep block. Independent girl. So she seems nice and didn't try to rush me off even though she needed to get to the staff meeting. I had forgotten about that until I saw her rushing off the the staff room after we left. Oops.
