Parenting tips: the importance of consistency: "Keeping regular routines with a child is also an important part of consistency. Days are less chaotic and arguments more infrequent if a child knows what is expected of them upon rising, after school, or when going to bed. Consistency helps a child develop a sense of responsibility in that they know exactly what is required of them.
Children are also less likely to test boundaries or push limits that are firmly set when they know that there will be consequences for deviant behavior. They learn that “no” means “no.” Consistency teaches children cause-and-effect relationships, which helps them as they grow with their ability to make wiser decisions."
