What is the best way to understand the children problem (especially kids)?
Be a kid and become his friend. By this way, he will feel more free and comfort to tell us his problems.
Problem with many kids is that they are afraid of telling many things to parents thinking they will get scoldings and beatings in return.
When he tell something, let us encourage him and show interest in his talks. Never scold for minor mistakes. Just smile for such silly mistakes. Gradually, your kid will lose fear to tell us a mistake committed by him and it will increase the bond of relationship as well.
Best method to bring up kids is to develop a feeling in him, a mental support at every bad time he face.
