Hi... Please correct his psychosocial environment to bring change in his behavior. Kids usually express their emotions in the form of tantrums, anger, or rudeness. Part of it is acquired and some of it is innate. We as humans need to be taught to express and deal with our emotions. Typically we learn it through imitation of our role models, parents, siblings, peers, seniors, teachers, etc. through or social interaction. But in some cases a conflict may occur and a kid may need an adult intervention to help them correct their perception and dealing with their own emotions. Sitting along with your kid every day for half n hour everyday, listening to his irrational talks and daily experiences, etc. goes a long way than any expert opinion. Try modelling the behaviors you want your kid to imbibe.
