We live in a rainforest, so we have many, many dark and/or rainy days (over 300 days a year). We are outside in it A LOT. We have to be or we would never get outside. We just get good gear and get out there. We also do a lot of winter camping and hiking.
But I also have a great little book I just picked up called "Cabin Fever Relievers". There are seven chapters detailing ideas from kitchen "messes" to garage action games to dramas and storytelling. One that I think we'll try soon is "Dinner at the White House" (we might change the title) where we get all dressed up and display our newly honed manners after practicing them for a few days ahead of time, so there's not much correction needed. Might be a good night to order in!
There are also a few activities in sensitivity training for kids... such as doing a type of sensory deprivation for them to understand what it's lke to be blind, deaf, or even just have a broken leg. Get crutches, blindfolds, and let them figure out solutions to their dilemmas, offering lots of time for being thankful for their good health or blessedness, For my girls, it woudl also be great for learning that they COULD do without something if they ever have to. They wouldn't just curl up and die if they couldn't hear or see or talk....
We also do most of our Dad-led projects during the winter. He gets all the supplies organized in the garage and they work with him for hours on the littlest things. They've already started making their sleds for the winter.... It ought to be interesting when they head up the hill on the first test-drive... yikes! DH is a big fan of letting them learn by consequences.
Thanks for this post! Hope to see some more great ideas!
