Discipline is necessary but should be done with love. Focus on the positive. Use consistency. Do not use negative emotions.
I broke my arm and was out of work for 6 weeks. When I took my clearance to go back to work to my supervisor, I wondered if it was worth it to go back. I had to go through a small amount of retraining. My supervisor acted elated and let me know I was needed. I was validated. Money didn’t seem to matter. I must be doing well in my work.
I took my dog to a training class. What did I learn? Reprove with sharpness when necessary, yes. I needed mostly to shower praise and love whenever my doggy pal did anything right. Yelling and hitting will only cower and confuse a dog. It may learn to avoid you. I have worked with horses and this is true for them also. You must be firm but patient and let them know when they are doing well.
How does this relate to children? A great deal. Children are smarter than animals. But many of the same techniques work for them. We need to focus on being positive and validating there efforts. They need to know they are loved no matter what. You must be firm and patient. Set boundaries and then be constant with consequences. You can simply use the phrase, “I am sorry but you made this choice.” Avoid yelling and hitting because at the vary least, it will put a barrier between you and your child. It could drive them away or cause rebellion. In other words, discipline with love.
