Show this excellent video to your children and try to help them grasp how the world was before they were born just a few decades ago. Use it to help them understand why we want them to go out and play, to explore, to take risks (according to their age, of course).
We have to always remind ourselves that we are not raising children, we are raising confident, centered and independent adults that, in just a few years, will have to fend for themselves in this complicated world. We can only hope and pray that we do a good enough job, so they can lead a fulfilling and joyful rest of their lives.
Enjoy!
