I got a phone call from DS form teacher yesterday saying DS (6 yo) has been teaching other children the middle finger in assembly. She said the head teacher had to tell him 3 times to stop. The most worrying thing for me is how out of character this is. He is such a kind natured child so polite and I am so shocked that this has happened. I'm really struggling with what punishment to give as it's such a horrible thing for him to be doing but so unlike him? He said he was told to do it by someone a year younger(!!). Any advice on how to make him learn and discipline him would be greatly appreciated!
