This paragraph refers to the amount of overprotection present in modern parents. Many parents are so worried about the idea that their child may end up injured in some fashion that they are not willing to let their children romp and play as a child should. Parents will bend over backward to ensure that their children remain safe throughout their life, but this intense bubble wrapping prevents them from learning about the dangers of living through personal experiences. Many parents also force their children to take part in activities the child is not particularly fond of because the parent never got to do it themselves. A parent may force their child to play the violin because they want their child to become a great violinist not because the child wants to do it.
