A love for nature need to be reinforced early and often. Most of my tips for camping apply to the older crowd as scouting doesn't often recruit 14 month olds. At the risk of sounding like a hippy liberal pansy perform some token conservation of your campsite while your there and pretend to enjoy it. Your son will learn from your habbits. Also, yeah, digital camera, especially if you have a young child. Don't want to go to jail for years trying to develop pictures of your kids at Walmart.
