Following are some key areas I feel you should spend ample time on with your kid(s) and most important, you must always be:
FAIR, FIRM AND CONSISTENT 

WHEN DISCIPLINING YOUR KID(S) IT IS ABSOLUTELY MOST IMPORTANT THAT BOTH PARENTS ARE FULLY IN AGREEMENT WITH EACH OTHER!  OTHERWISE EVERYONE LOSES! 

You should "Keep in Mind" that:  
#1.  Your child is the best salesperson on the planet 

#2.  Effective child discipline focuses on guiding behavior through clear rules, consistency, and positive reinforcement, rather than punishment, by modeling calm behavior, using natural consequences, validating feelings, and catching kids doing good to teach self-discipline and responsibility. Key strategies include setting age-appropriate limits, staying calm yourself, praising good actions, and following through with brief, consistent consequences (like time-outs or losing privileges) when rules are broken, teaching empathy and problem-solving along the way.

#3. You must never make excuses for your child's inappropriate behavior.  You can rest assured that if you do, the world will stepin and your child will pay for your inactions.  This is not an option!

Following Are Some Core Instructions for Parents

Integrate Teaching into Daily Life: In Deuteronomy 6:7, God commands parents to talk about His words "when you sit at home and when you walk along the road, when you lie down and when you get up." This suggests that teaching should be a natural, ongoing conversation rather than just a formal lesson.

Lead by Example: Before teaching children, parents are told to have God's words on their own hearts first (Deuteronomy 6:6). Children learn most effectively by imitating their parents' conduct and sincerity.

Provide Nurture and Discipline: Ephesians 6:4 instructs fathers to avoid provoking children to anger and instead bring them up in the "discipline and instruction of the Lord".

Establish a Foundational Path: Proverbs 22:6 states, "Train up a child in the way he should go; even when he is old he will not depart from it," emphasizing the lifelong impact of early training. 

Key Subjects to Teach

Love for God: The primary lesson is to love God with all one's heart, soul, and strength (Deuteronomy 6:5).

God’s History and Deeds: Parents are urged to tell the "next generation the praiseworthy deeds of the Lord" so they may put their trust in Him (Psalm 78:4-7).

Moral Responsibility: Teaching should include values like telling the truth, seeking wisdom, and working diligently (Proverbs 4:5; Proverbs 6:6).

Prayer: Just as the Apostle Paul encourages believers to "pray without ceasing" (1 Thessalonians 5:17), parents are encouraged to model and teach prayer as a foundational habit. 

Parental Attitude and Conduct

Gentleness: Parents are warned not to embitter or discourage their children (Colossians 3:21).

Diligence: Teaching is described as a task to be performed "diligently," requiring consistent effort and focus.

Stewardship: Children are seen as a "heritage" or gift from God (Psalm 127:3), and parents act as temporary stewards of their lives. RAISING children is the absolute most important thing anyone can do. ABSOLUTELY!

Some ways kids show defiance!
Defiance in children often manifests as a deliberate push against authority, rules, and expectations. While occasional defiance is a normal developmental phase—particularly during toddlerhood and early adolescence—it can become a concern if it is persistent and interferes with daily functioning. 

Common Behavioral Signs

Active Refusal: Flatly refusing to comply with adult requests, instructions, or household rules.

Excessive Arguing: Engaging in frequent, intense arguments with parents, teachers, or other authority figures, even over minor issues.

Questioning Rules: Constantly challenging why a rule exists or negotiating for exceptions (e.g., arguing for "just 15 more minutes" at bedtime).

Deliberate Annoying: Purposely doing things to upset or irritate others, such as making noise or interfering with someone else’s activity.  You have seen this many times.  You have a couple choices:
  
#1. You may choose to ignore the child but this is not always possible.

#2. You may need to confront the child and instruct him/her to stop. If he/she does not comply, you must decide on an consistent consequences (like time-outs or losing privileges) when rules are broken, teaching empathy and problem-solving along the way.

 Blame-Shifting: Refusing to take responsibility for their own mistakes or misbehavior and instead blaming others. 

Emotional and Verbal Indicators

Angry Outbursts: Frequent temper tantrums, yelling, or screaming, often out of proportion to the situation.

Hateful Language: Using mean, harsh, or unkind tones when upset to hurt others' feelings.

Vindictiveness: Seeking revenge or acting in a spiteful manner toward those who have upset them.

Irritability: Being "touchy" or easily annoyed by people and surroundings. 

Age-Specific Defiance

Toddlers (1–3 years): Defiance often looks like physical resistance (hitting, biting, or falling to the floor) as they struggle to assert independence.  This may be a great time to simply ignore this behavior!  Just let the child go through this without your interference.  Yep!  This is extremely hard to do.  People are watching, you are embarrassed.  This is a time when you must decide which is most important, your child's future, (that's exactly what we are talking about) or the fact that YOU are embarrassed.  Big Decision!  Decide Carefully!

Preschoolers (3–5 years): They may frequently say "no," refuse to share toys, or whine to avoid following directions.  Here you must again step in. Explain to your child what it means to share.  Create an example that he/she can understand.  If he starts to whine, let him go through the process.  Whining is tiring, most often after whining the child may want to sleep.  

School-Age (6–12 years): Defiance often moves toward verbal negotiation, questioning authority, and sometimes neglecting school assignments or chores. OK!  This type of behavior also requires your immediate attention.  You must reassert your authority.  

If these behaviors occur almost daily for more than six months and significantly impact family or school life, they may be signs of Oppositional Defiant Disorder (ODD), which often requires professional support.

Note! My career that expanded over 40 years and in the U. S. Military and with the California Department of Corrections.

During that time, I work with young and older men and women from around the world for more than 40 plus years and I am certain that much of my success was because of the following (make no mistake, the military receive a large number of young men as women who were poorly trained by their parents and the school system)!: 

#1.  I would not compromise my values.

#2: I had an internal compass that was provided to me by "My Six Pack!" - An internal compass refers to both a literal neurological system in the brain that tracks direction using neurons head-direction cells and a metaphorical sense of personal guidance based on core values, intuition, and goals, helping you navigate life's decisions and stay true to yourself, distinct from external opinions. It's your innate sense of "north" for making choices, whether you're finding your way in a physical space or charting your life's path.  

#3.  I follow my "Gut Feelings" far more than I followed "the Rules!"

Don't misunderstand what I am saying.  I have made my share of mistakes during my life and career, AWOL in the military, disobeying direct orders, and a few other policy violations and yet, I have never received any documented chastisement.  WHY, because in every case, the system and my superiors always knew that what I did was because of the following:

#1.  I immediately excepted full responsibility for my actions and because in every case, (except one), I did what I did, not for myself but for one or all my soldiers.  

#2.  They knew I truly felt that what I did was with the best interest of my soldiers and that I knew the possible consequences of my actions and still decided to move forward.

Let me be clear!

I am absolutely convinced that my success in life was NOT from what I learned in the military and during my time with the California Department of Corrections.  I am convinced that my success was at least 95% the result of what I learn long before I entered VA State University, the U. S. Military and the world BUT was because of what I learned from the following:

#1.  "My Six Pack!" I had an internal moral compass that they provided to me 

#2:  I would not compromise my values.

#3.  I followed my "Gut Feelings" far more that I followed "the Rules!"

#4:  "Train up a child in the way he should go; even when he is old he will not depart from it," emphasizing the lifelong impact of early training. - Proverbs 22:6  

Why is this important when raising children?  

Children (Kids), Learn What They Live!   

Following is a simple example of something I want you to consider:
You are driving down the road and your child, maybe 7 years old is setting in the back seat.  You are speeding, (they can usually tell simply by their feelings, you pull up to a stop sign but do not stop, you just roll through).  

A few years lated your child is sixteen and wants to have a car and you feel this may be a good idea because it will save you lots of time and that's what most other kids are doing.  But you being somewhat concern you decide to tell your child about some of the rules of the highway.  Following are some of the first things you are going to say to your child:

#1.  No Speeding
#2.  Be sure to stop at all stop signs
#3.  No illegal parking
#4.  And on and on ...

Here is what I want you to understand - Your child is far more likely to drive the way they saw you drive than drive the way you tell them about how to drive.  Ignore this at your own parallel.  

Core Instructions for Parents - (Most of the biblical references are from AI) and I am not preaching here but I do think AI's choices of references are worthy here!

Integrate Teaching into Daily Life: In Deuteronomy 6:7, God commands parents to talk about His words "when you sit at home and when you walk along the road, when you lie down and when you get up." This suggests that teaching should be a natural, ongoing conversation rather than just a formal lesson.  My son would often tell me to Give him a break - Get out of hi sears!  I never did!  I still get into his ears!  

Lead by Example: Before teaching children, parents are told to have God's words on their own hearts first (Deuteronomy 6:6). Children learn most effectively by imitating their parents' conduct and sincerity.  Trust Me!  This is critical.  the first thing I learn as an Infantry Officer in the military, "Follow Me!"  

Provide Nurture and Discipline: Ephesians 6:4 instructs fathers to avoid provoking children to anger and instead bring them up in the "discipline and instruction of the Lord".  There is an old saying, "He who get angry first, looses."  I am not sure if I totally agree with this or not but I do know that agree often times blinds your thinking! 

Establish a Foundational Path: Proverbs 22:6 states, "Train up a child in the way he should go; even when he is old he will not depart from it," emphasizing the lifelong impact of early training.  One or more of the members of "My Six Pack" has been on my shoulders almost every day of my life!  Thank God they were!  

Key Subjects to Teach

Love for God: The primary lesson is to love God with all one's heart, soul, and strength (Deuteronomy 6:5). 

God’s History and Deeds: Parents are urged to tell the "next generation the praiseworthy deeds of the Lord" so they may put their trust in Him (Psalm 78:4-7).  Recently I told my granddaughter that I would never tell her a lie.  I also told her that I would never repeat anything she told me in confidence unless I felt that it was very necessary to do otherwise!  

Moral Responsibility: Teaching should include values like telling the truth, seeking wisdom, and working diligently (Proverbs 4:5; Proverbs 6:6).  During my time with my granddaughter(s), never enough I try and make it a point to tell at least one story that reaffirms the foregoing!  See godowdy.com/fight (will be posted soon!)

Prayer: Just as the Apostle Paul encourages believers to "pray without ceasing" (1 Thessalonians 5:17), parents are encouraged to model and teach prayer as a foundational habit. 

Parental Attitude and Conduct

Gentleness: Parents are warned not to embitter or discourage their children (Colossians 3:21).

Stewardship: Children are seen as a "heritage" or gift from God (Psalm 127:3), and parents act as temporary stewards of their lives.

"Kids Learn What They Live." - refers to the powerful parenting principle, famously captured in Dorothy Law Nolte's poem, that children internalize the behaviors, attitudes, and emotions modeled by the adults in their environment, learning condemnation (the expression of very strong disapproval; censure) from criticism, confidence from encouragement, and love from acceptance, shaping their character and worldview. This concept highlights that upbringing, not just instruction, teaches children fundamental life lessons and values, emphasizing the importance of positive role modeling for healthy development. 

Don't get me wrong!  I an not saying that you are the problem your kid is unruly; however, what is being said is this:  We as parents must be careful of how we react to the actions of our kids.  I believe the most effective form of discipline is the practice of training your kids to obey rules or a code of behavior, with punishment, (Never Physical Punishment), or other undesired consequences for those failing to comply.  

You absolutely MUST be Fair, Firm and Consistent!  This is CRITICAL!

This old Proverb still rings true:  "Train up a child in the way he should go; even when he is old he will not depart from it," emphasizing the lifelong impact of early training. - Proverbs 22:6
