We left Z alone and she wandered off and started jumping off the high dive at the pool. Quite a surprise for our normally conservative Z! The fact that she did it without any prodding or encouragement for us was surprising. Good job, kid! She told me that she stands on the edge and thinks through how she wants to land, on which part of her body, and then drops off the edge. She loves it.As soon as A heard the high dive was open, she went back into the pool. As you can see she walked right out the end, didn't really think about it and jumped off. This is pretty typical for A... fearless. I asked her if she was afraid and she said, "Not until after I jumped." She jumped twice, but isn't quite as sold as Z on this being a fun activity.
