I just witnessed DD's class teacher having a word at pick-up time with someone who I think is the grandmother of another girl in DD's class. The teacher was obviously very angry about this little girl's misbehaviour because she was raising her voice a bit and looked very cross.
Two minutes later the grandmother was telling the little girl off good and proper - so much so that the child had a screaming meltdown tantrum on the pavement opposite school. Grandmother hit the little girl and threatened her with a cold shower.
Poor, poor little girl. She is adopted and has some developmental/behavioural issues. But that doesn't seem like the right way to go about helping her overcome them...
