most of the time they need ATTENTION or the parents need to find the root cause of the problem it could be all the sugar or caffeine they allow their kids to have. I never understood how people can give their kids soda pop at young as 2 or three . I have seen some in baby bottles really that is nuts . It is parenting styles it is the environment they react to the environment they are in. When things are not working in my own house hold I find the cause whether it be someone at school influencing my kids whether there is to much arguing or yelling in the house or what ever . when a child starts acting different there is a reason .
