"Helicopter parents" is a description of parents who are hovering over their children in a state of extreme concern. They always show up to solve their children's problems, protect them from real or imagined harm, resolve stressful situation, offer advice and get them out of trouble, even if they misbehaved. Although out of love and concern, it can have harmful effect on their children's emotional development and future autonomy.
Children learn through their mistakes. But if you intervene (介入) at first sign of struggle and finish your child's homework, he'll miss out on valuable learning opportunities. You're sending him the message that he needs to be perfect and failure is not an option, otherwise you wouldn't always take over for him.
By constantly rescuing your child from stressful situation, you're sending him a message that you don't believe he's capable of taking care of himself. Children develop self-esteem by learning how to complete challenge on their own. If you are always intervening, he's denied this vital stage in his growth. As a result, your child may lack the confidence necessary to do well in school, pursue hobbies and interests, and develop friendships.
If you're always taking care of everything for your child, it'll be more difficult for him to become independent. As an adult, he might find it hard to take care of himself, because he's never developed coping skills to deal with life's challenges. He might suffer from irrational fears, anxiety and depression, which could lead him to drop out of college or frequently change jobs, according to Dr. Michele Borba. Instead of developing healthy relationships, he might seek a partner who will take care of him or controlling, as his parents were.
You can help your child become more independent by allowing him to complete tasks and challenges on his own without your intervention. Even if he fails at first 
don't interfere—encourage him to start again. Show that you have faith in his abilities to succeed without your help. Allow him to learn natural consequences. Even small things can help him become more independent—making his own bed, preparing his own lunch, shopping for his own clothes and doing homework without your help.
