Hi Diana,
Sounds like DD is in excellent shape to take on the stress of having a "famous" brother, when and if further acceleration brings him into her sphere. She sounds like a terrific kid, well able to withstand the flack of being "lapped" by her younger brother. I think that fact that she is well liked but contentedly "not popular" is a good indicator that she is comfortable in her skin.
I'm the oldest in a family of 4, the last two being twin boys. I have a tiny taste of being famous by proxy. My middle brother got much more than a taste, being only 2.5 years older - he was sometimes refered to as: "the twins' brother!" Ohh he hated that! I propose that having a different level of gifted sibling is much like having twins in your family - it just happens sometimes: Parent behavior can minimize the effect or play it up to a degree, but in the long run it's just part of what life hands us.
((warm smile))
