It depends on what you mean by "growing up." If you mean to ask if children are maturing too quickly, then no. If you mean to ask if they're being asked to become aware of and understand more than they are capable about understanding about the world, then yes. And yes, parents have a LOT to do with how quickly children "grow up." In my very humble opinion, I think children should be allowed to be children. That means that they should be allowed to enjoy the world and their place in it, they should feel loved and protected, and they should carry little responsibility other than to learn to become good and whole people. This does NOT mean that they should be sheltered unnecessarily or lied to about what really happens in the world. But let them be children while you're teaching them to be grown ups. Otherwise, they miss out on a whole lot of joy in life.
