How do I stop my child from hitting other kids?

I will give him negative reinforcement if he hurts others. I will remove things that he likes or must have if he hurts others. This will make him stop n think whenever he wants to hit. I will also design a reward card system. He will get something he rarely gets and really likes for eg a toy, if he can control himself by not hitting for 3 days (start small and achievable). Then prolonged the reward. This usually works for young children.
