My daughter (2.5 yrs old) has recently started gaining interest in walking herself on trails instead of riding in the backpack carrier. On our last hike, she was trying to pass through by using a large rock on the side of a trail since the middle of the trail was muddy. She fell off and got muddy. She got up and said "I want to do it again, and this time not fall." So she got up, tried to cross again using the rock and was successful. She was so proud of herself! It's the first time I've seen such perserverance from her. One of my favorite outdoor moments ever.
