Geez... sorry, but the school can't expect 4 year olds to act like robots.
He is not the only 4 year old... that does not always listen.
He is going to get defeated anytime he "tries his best..." because it will NEVER be, good enough. It is endless... calling him a bad listener and that therefore, he has "bad behavior." So then he won't even try. Why try... because he is always scrutinized for his not listening.
I think, it is just going to undermine him, all this focus on him not listening.
Sooner or later, the incentives of a green apple, won't even work. Because NO kid, can be "perfect" nor have perfect listening ears.
He seems like a normal 4 year old to me.
Who is trying his best... but his best is not good enough.
I would hope, that he does not start acting out... just out of frustration. Then this will be a "problem." But because of misaligned "expectations."
all the best,
Susan
