With that said I feel comfortable saying that, for now at least, my daughters seem to have distinctive differences in the introvert/extrovert categories. This is very different from shy or outgoing. Introverts simply get their energy from a little time to themselves. Extroverts are energized by being around others. Of course there is a broad spectrum here and some are right in the middle.
It is safe today that my husband is introverted and that I am extroverted. This balance works really well for us! We seem to have each passed our disposition down to a child.
This was exemplified yesterday after visiting the Ucross ranchhouse and then hiking around for a bit. Cordelia was eager to explore and meet the other people around the compound. Elise told me that she just needed to relax for a bit before going back out.
Eventually Cordelia coaxed Elise outside to play with the promise that they would soon snuggle.
I couldn't help but laugh at their differences. I do hope this helps them both to grow and challenge each other as they move through life.
