Our responsible child

Even within the same family, each child has their own personality which can vary quite drastically from the rest some are shy and introverted, others are boisterous and loud, while another could be caring and considerate. What does this say about the nature vs nurture discussion? Not very sure actually not sure why I brought that up.

Aiming to conquer the world!
In ours, we are lucky that we seem to have one child who seems to be developing in a way which comes across as responsible, accountable to herself and generally quite self-motivated. The keyword here is quite as she sometimes still lapses into moments of child-like behaviour which is understandable since she is, basically, still a child. Which begs the question, when does a child stop being a child?

A second child has an advantage over the first, based on my observations and logical conclusions. She can look at whats happening with the eldest in the family, learn from his mistakes, avoid the scenarios where she would get big-time scolding (not always successful) and become an improved version to the best of her ability. In that same line of thinking, the third child, and so on, would end up becoming more and more perfect. We have yet to see that happening, but things could change thats just a theory.

So far, our responsible child does her homework more diligently, often without being told, strives for (some version of) perfection and sets expectations for herself. She has a healthy sense of competition with her peers and tries to outdo herself when she can. What more can we ask of her? I would say, keep it up Shannon the only way to success is to keep trying.
