So, when he is not 'nice'.... why is that?
What are the triggers?
Is he tired?
Hungry?
Bored?
Just testing limits?
Just doing it for the heck of it?
He is 5.
You can talk to him too.
Hand in hand with 'punishments' or discipline... is, also teaching a child about what their part in it is. And that they are a part of a family. There is "Teamwork". There is helping. There is responsibility. There is chores.
There is, doing things because that is the way it is. Not just because you get a reward for it or not.
Once a child goes to school, they do get influenced by things and other kids.
SO.... you also need to teach a child, HOW to cope, HOW to problem solve, HOW to 'discern' what is good/bad/inappropriate. Because otherwise, they don't learn that. They only learn 'reactionary' things... not the 'why' of it.
A good book is "Have A New Kid By Friday" by Leman. And, "How to Talk So Kids Will Listen, and Listen so Kids Will Talk."
It is not only 'expecting' a child to act a certain way... but for the parent to also learn... how to trouble-shoot for their kid. How to manage these things. In a positive way.
Punishments/discipline alone... it not full-circle. It does not teach a child, why or how come... it just teaches them that they get punished per the tolerance of their parent.
Also, no child is perfect.
My late Dad.... his take on it was this: Although he was no push-over... he said that a child needs to learn.... how to express themselves. AND they need to KNOW, that their Parents and their home... was a 'safe' place to vent/have issues/and to talk about problems. Otherwise, a child will have NO WHERE to let their hair down and deflate. And that, the Parent is not just a "ruler" with a stick. You need to have a 'relationship' with your child... to understand them and accept them... Good OR bad... and that, they can come to you, for anything. At home.
If expected to be "perfect" all the time everywhere, then WHERE can a child make 'mistakes' and learn???? Without fear?
all the best,
