A child without TERRIBLE TWOS is a worry for the future. If you force your child to shut up and dominate him with fear, thinking it is discipline at this ages, quite possibly he will have mental problems as an adult. TERRIBLE TWOS is an important part of growth to establish the ego. If this is forcefully stopped, a personality with low self-esteem will be formed. And it is possible that they learn during this period that it is right to dominate others through fear. Then they will become adults with no end of interpersonal troubles.
