Children develop through stages, and these stages come at roughly about the same time (within a year or two of other children). If the stages are slow, we have arrested mental development.
Because of this, we often forget that children develop aspects of their mental understanding of the world in stages, not all at once. Children do not slowly get "better and better" at discerning things, they become ABLE to discern things that they could not before.
Much research shows quite conclusively that if a child is too young, she cannot understand another's point of view; she only sees the world through her eyes, and is unable to truly comprehend another's feelings or emotions. Therefore, trying to "reason" with her about how it makes Tommy feel is an exercise in futility; we do it because we don't know exactly when she can start to understand, but she just might not be able to no matter how well we explain.
Therefore, at this age, no form of "reasoning" will suffice to modify bad behavior; another method is necessary. Although physical punishment is not absolutely necessary, it is the most convenient and it often is the most effective. Children immediately understand and associate pain with experiences. Although some may get confused, many children immediately associate pain with a poor behavior if the punishment comes immediately and it is explained directly (not "reasoned.")
This is very wise and so true.
For example:
Sarah gets up and throws a toy at Tommy, and takes his toy. Within a minute, Sarah's mom says, "Sarah! Do not throw toys at people, and don't take his toys, they aren't yours! You did a bad thing! I'm going to spank you to teach you that's bad!" She immediately spanks Sarah several times. Sarah may repeat this behavior at a later date, and if Sarah's mom repeats, Sarah will learn quickly that throwing a toy at someone = spanking. Spanking = pain, pain = unwanted, and so throwing a toy at someone = unwanted.
Later, Sarah will become able to understand why it's bad (it hurts other people).
I only hope that Sarah's mommy will take her aside in private to correct her.
Public humiliation is uncalled for and unnecessary.
It takes extra effort and sacrifice on the part of the parent
to stop what you're doing and find a private place to correct the child,
but when the child learns that you are willing to do whatever it takes,
they learn not to cross the line.
If I was out shopping with my child,
we would retreat to the restroom.
I always carried a little rod in my bag.
The most important thing I learned in the parenting classes I attended was that
I had the right, the authority, even the responsibility to expect absolute obedience from my child.
As someone has already said,
it is quite a relief, as your child is headed into the street,
to have them instantly obey when you say, "No!"
By the way, it is also a fact that a disobedient child will not be potty trained.
You cannot teach them anything unless you bribe them or manipulate them into learning it.
It is not a pleasant way to live.
The rod and reproof give wisdom,
but a child left to himself brings shame to his mother.
Proverbs 29:15 ESV
