Some kids just don't know how to bring themselves down and need help to do that. Which has nothing to do with your [arenting at all. In the end, the only way you can tell if your child is needing your help to deal with overwhelming emotions or not is to observe the child and trust you parenting instincts. You are the expert on your child.
FWIW, my oldest had tremendous tantrums for quite a while, and still does occationally, but he is getting better and better and he has learned some skills in getting himself calm, exiting situations when it gets overwhelming, etc. It hasn't been easy, and I have had many people tell me I was doing the wrong thing. I just knew he needed my help. My payoff has been how senisitve he is with other children, particularly his younger brothers, and how comfortable he is in expressing how he feels - in words rather than wails.
Listen to your parenting instincts, you know your child.
