I think childless people have an unbiased perspective which is valuable. When I watch a spoiled child throw a tantrum, it’s obvious to me how the child was conditioned to behave that way. The parent denies the kid something and it cries. Parent feels bad and gives the kid the toy. The kid just learned a pattern. Next time the kid does it again and it works. Next time the parent says no and is firm on that position. The kid cries more intensely. Parent freaks out because the intensity is new to them so they give in. Now the kid learned to raise the intensity. It’s like the experiment that was done on rats where they were conditioned to press a lever for cocaine. Before that behavior can be eliminated, it intensifies. The rats would smash the lever repeatedly. That’s when parents usually fail and they fail because they’re emotional when they see their child cry. Raising a child isn’t very different from raising a dog. Keep in mind that ALL behavior is learned. A child screeching and kicking at the store for a toy is not instinctual. A parent may not see how they are training their child to behave that way and most other parents have kids that do similar things. That’s why getting advice from non parents can be very helpful.
