Replies to 'Too Much Discipline?'

Your concern is valid and reasonable. Your son is only 6, but he is learning behaviors that could negatively affect his life forever. I believe that seeking professional help is the best thing you can do at this time, for your son and for yourself. The fact that your son has no concern for others if he hurts/insults them is a big, red flag that there is something wrong.
If you watch Dr. Phil on a regular basis, you know what he recommends when a child is out of control. He advises parents not to simply take away toys, etc.- he has them totally clear out the child’s room, only leaving the bed, a blanket and pillow. From there, the child has to earn back everything. On a daily basis, if your son behaves himself, then he will get his lamp back. The next day, another blanket- you get the picture. You work on the essentials first, then the toys. The toys always come last. This way, the child has more time without them, hopefully this time will help him to realize that having nothing really sucks.
I know that this punishment will effect you in negative ways, also; but it is so important, because you are taking action to change his whole life. This isn’t just for now; this is to influence the rest of his life on earth.
His father is doing his child harm by allowing him to have so much power. By not giving his child consequences, no responsibility, no reason to care about anything, he is setting him up for failure in life. When your child grows up and goes out into the real world, he will be faced with people who don’t give him everything he wants, people who don’t jump when he says jump; then what happens to him? Giving the child some responsibility and accountability is the best thing that could happen to him.
Question: this meeting that is coming up, will your ex be attending?
I wish you the very best. All you can do is your best- you live and learn.
