As a child, I always introduced myself to trees and plants when we moved to a new house. I believed that plants and trees could communicate telepathically with me and each other. I'd ask them if the trees at our last house had told them I was coming, etc. If I found a broken leaf or a plant in trouble, I'd try to nurse it back to health.
My son is five and I still walk around naked in front of him. He\'s natural and comfortable about it, hardly seems to notice. I still help him out in the shower, etc. I figure I\'ll see his cues when its time to stop. In Japan whole families bathe naked together. I think that each family is different, but in my house it\'s not an issue. My parents were always matter-of-fact about their own nudity when I was a child, and it\'s simply not a big deal to me.
