It sounds like you are experiencing a common challenge many parents face when it comes to teaching their children right from wrong and helping them develop good character. It can be difficult to know how to handle situations like this, but it's important to remember that children are still learning and developing their understanding of right and wrong. It's natural to get frustrated and upset in these situations, but it's important to try to stay calm and find ways to teach your child without relying on punishment or scolding. One option could be to have a discussion with your child about honesty and why it's important to tell the truth, and to try to understand why they felt the need to lie. It's also a good idea to set clear boundaries and consequences for misbehavior, and to consistently follow through with them in a firm but loving way. It's a tough job, but with patience and understanding, you can help your child learn and grow into a responsible and honest adult.
