My 5, nearly 6, year old son has been having continuing beahvioural problems at school. At home we don't have many issues with him at all, he is quite active and rarely sits still but does entertain himself and is generally well behaved. He attends dance and swimming classes and rarely has problems there as well. He is in Kindergarten at school and he is academically smart and does well with maths, reading and writing. His behavioural problems are usually concerning other boys - he is rough in the playground, we have just received a note home saying he hit two boys heads together, I have been called to the school on 3 occasions concerning him having hit his head, last week he stole 20c from a girl after school while waiting for my husband to pick him up then he lied about it 5 times before he told the teacher the truth, these are just a few of the many issues that have occurred at school this year. We have been to see his teacher on numerous occasions to work out strategies on how to deal with him. Our difficulty is that he is not the same at home and it is hard for us to discipline him for behaviour that he has done at school. We have tried behaviour charts that have worked for a while but he loses interest quickly. He doesnt seem concerned of consequences nor concerned that he is constantly in trouble. He has an older sister who is 10, we have had no issues with her ever at school. Any advice would be appreciated we are at a loss of what to do.
