Is there a particular situation in where your child misbehaves, or does the child just not listen? Can you be more specific in your issue? You don’t have to share your answer with the CR, but you do need to know the answer for yourself.
You should have a mechanech that you can discuss your chinuch issues with. You need to give positive reinforcement in a much larger proportion than negative. That means, that you should reward positive behavior, much more often than you would punish negative behaviors. Chazal say the left hand pushes away and the right one (the stronger one)brings closer.
My favorite book for chinuch is Make Me Don’t Break Me, by R. Moshe Gans. To be honest I haven’t read all the new books, but trust me, it’s a classic.
