I think we are perhaps all in danger of over thinking this a wee bit too much? It's just primary school. In my school, Dd often has to wait her turn, sometimes (often?) other children take priority, she does encounter "enormous" children and is great friend with them, the head does not stand in the very same place at the very same time everyday as he is busy running an enormous, multi cultural, vibrant school. And guess what, she's happy, I am happy, and yes she can read and count despite me not chatting to the head every day! I know it's a stressful time for new parents but please don't feed the angst. It's a nice area, the schools are ok. The kids will be all right.
