Rules and boundaries are important for young children for a number of reasons:
They provide a sense of security and predictability. Children thrive on routine and structure. Rules and boundaries give them a sense of security and predictability, knowing what is expected of them and what will happen if they follow or break the rules.
They teach children right from wrong. Rules and boundaries help children learn about right and wrong. They learn what behaviours are acceptable and what behaviours are not. This helps them to develop their moral compass.
They help children learn self-control. Rules and boundaries help children learn self-control. They learn to delay gratification and to control their impulses. This is an important skill for them to develop as they grow older.
They help children learn to respect others. Rules and boundaries help children learn to respect others. They learn that their actions have consequences and that they need to consider the impact of their behaviour on others.
They help children develop independence. As children learn to follow rules and boundaries, they are also learning to develop independence. They learn to make choices and to take responsibility for their actions.
