Our child learns the world. The correct reaction of loving and caring daddies and mothers to children's questions plays a very important role in the process of this cognition. This question is quite serious, but still there are some fairly simple recommendations.
So:
1. If you do not know the exact answer to any tricky child's question (after all, very often children ask unexpected and tricky questions), sincerely tell your child about it. Explain to the kid what you need to read, understand and find
The correct answer to the question that interests him now. Just do not count on the fact that your child will forget about what interested him so much, and if you have already promised to answer, answer.
2. Encourage your child to enter into dialogue with you. Ask him leading counter questions, train him to reason with you.
3. Cultivate your child's imaginative perception of the world around him. Use comparisons and metaphors in your answers and explanations. Give your child answers to questions of interest to him in a form that is understandable to him.
4. No need to answer "for show". Perhaps the child will remember well the knowingly incorrect or evasive answer to the question asked, but will it benefit him? The child needs to be answered sincerely, to present the most reliable information in an accessible form. Your kid can invent an absurd and incorrect explanation himself.
Love your kids, answer their tricky and not very tricky questions, develop your children and be happy!
