I have an idea. I was a kid loooong before TV, Internet, Facebook, XBOX or ANY other modern day electronic devices. While inside we played board games, drew pictures, played card games or helped our parents with household chores. I built model airplanes and learned how to carve animals from blocks of wood. I built fantastic mechanical devices from my Erector set - I learned wood burning to make wonderful pictures. We would listen to the radio - Lone Ranger, Tom Mix, the Shadow - but sadly all those programs have died with the past. I learned how to take and process pictures with a film camera. I learned Morse Code and how to operate a simple Ham radio. I built my own Ham radio from a Heath Kit. I learned how to build and erect my own wire Ham radio antennae.
I started seeds in pots, in the house, that would later be transplanted to the family garden plot.
You have the great opportunity to teach your children that all entertainment need not come from modern electronics.
