They don't take 'threats' seriously.
Then, they also do not have the internal sense of just doing things out of respect or "for" Mommy etc.
Then, the kiddo also does not think any "punishment" is permanent. Because, in the end, they do get back what they wanted in the first place (and they know it), and they take for granted.
And it is then, not taken seriously, again. Vicious cycle.
Also, some kids just get desensitized, to any punishments etc.
And they don't learn, to just respect what is said to them, by the parent. Or only by a certain, parent.
ie: some kids will only listen to one parent or the other.
But also in school, some kids just will NOT listen, to anybody. Be it a school Teacher or Staff, etc.
And they know it... that they are not "behaving.' But they still do it, anyway.
I work at a school. I see this all the time. Even in the classrooms of the most seasoned teachers who have been teaching, for years.
But, the ones that do have a grasp of their students... from day ONE... state the rules and the consequences, and they do it. Not wavering.
And they do not, ply the kids with flowery pussy footing, around.
They state things, clearly and bluntly, and then, do it.
Per the classroom, rules.
I dunno, it is not easy.
But at this age and older, a kid has to learn, how to self-correct.
They know, right and wrong, mean and nice, by this age.
They, know.
I asked one kid at school where I work, WHY the heck does he, CONSTANTLY cause trouble, EVERY day? (and yes, he does literally cause trouble, EVERY DARN DAY... to the other kids. And he KNOWS, it) And he just does not know. He has no answer, to that. He just shrugged his shoulders and said "I don't know..." And yes, he gets notes sent home everyday, from the Teacher, and gets disciplined in school, and gets sent to the Principal and on and on. And he STILL, acts like a brat... every day. But he never takes it, seriously.
Who knows what the parents do with him, at home. Or from the day he was born. But this is how he is, and ever since he was in Kindergarten. I've seen it.
And he is not the only, one.
Anyway, do whatever you think will work with your kid.
That will work and bring a sense of consciousness, to her.
At some point, the behavior of a kid, needs to come from an internal sense of control...and respect to their parent.
When I was a kid, things were different and more old school.
Who knows if that was better or worse.
And inevitably, a kid needs to learn, character, not just about things.
And how to earn it.
Give your kid, CHORES... and a sense of WORKING toward something.
And GAINING self-respect and your respect, that way.
Kids need to learn, how to WORK for things... both externally and internally.
But you don't have to 'reward' the kid with "things" as rewards. Let her gain a sense of what hard work feels like... internally. And how that is a 'reward' in itself.
