I remember our son when he was almost 2 and a half hiking in the forest. He was little to take on a hike and I thought I would be carrying him but he liked to walk. We made sure we took it at his pace. He would stop to look at moss or at flowers. Sometimes he came to rocks bigger then he was and he would gamely try to climb. We went nearly 3 miles over rough terrain; roots, rocks, up and down. I want to persevere more in fighting the battle of negative thinking.
