Today DD (4) went to school for first time. Teacher and assistant did not introduce themselves to her but did introduce other kids by name. Then asked all kids to go in circle and sing Farmer wants a wife. One kid was chosen to be farmer by teacher and had to choose other child as wife, wife chose child, child chose nurse, nurse chose dog, dog chose bone until DD, teacher and assistant were left. DD clearly felt quite left out. I was surprised that teacher started off like this. Am I being unreasonable or could this be a sign of other things to come and should I look for other school?
