Am I a Helicopter parent?

I keep hearing the term, helicopter parent and more and more, I am getting the uncomfortable feeling that I have inadvertantly joined the ranks of hovering, swooping parents. I never meant to be this way, and I am not even sure I am . I definitly used to be. When Nate was a baby, I was so hypervigilant and anal retentive about parenting him; I never relaxed and enjoyed it.

I am hopeful that I have relaxed somewhat and let my children just be. I am engaging in discussions of Wendy Mogel's, Blessings of a Skinned Knee;" the uber parenting "it" book of the moment. I just can't seem to find the balance between caring, involved parent and helicopter parent.

To be fair, Nate does not seem to let me find a balance. When I go to drop him off someplace he hangs on and panics. For example, we are participating in a sports class 1 afternoon a week. All the other 4 year olds, walk in and join the class. My son sits with me and runs after me if I attempt to leave. He will not participate unless I do too. Now, is this a question of me hovering and giving in to his anxiety? What are my alternatives? If I just leave and let him freak out, like I used to at preschool, I would be leaving him with a coach who has 15 other kids to worry about. We are on the 3rd class and he is improving in participation each class. My hope is he will get better each time to the point I can drop him off.

I wish there was a test. Remember the Purity test back from high shool and college? It was about 100 questions asking questions ranging from drugs to sex. Add up your score to see how you rank in purity among your peers. I wish there was a Helicopter Parenting Test. It would ask questions like:
1. Do you co-sleep?
2. Did you make your own baby food?
3. When your child falls down, how quickly do you pick him up?

What questions would you have on a Helicopter parenting test? Consider this a call for questions? How would you score? Are you laid back, hyper-vigilant, neutral?
