Never hesitate to answer a child
Child is a very special to the universe, going deep down to the strengths of a child, they posses the ability to cogitate the new ideas. When ideas come to their mind, they start digging deep into it. In the process of happening they may ask many questions which are truly stupid, silly, very odd, often we Parents gets fire to answer those stupid questions, parents should try to understand, try to learn and give minimum knowledge that they have.
History has proven that stupid questions are somehow true in the real world that exists… it would happen only when we allow the child to think wide enough and free from school subjects, theoretical concepts.
