It's all about a healthy balance. I think it's important to make sure your children know that they can come to you with all their problems and openly share what they are going through but also know the consequences of the mistakes they make so it's good to be stern but understanding.
Its not a requirement, but its better also to be friends with your child so they will be comfortable sharing things with you. You should also put boundaries.
