Oh, she definitely is not comfortable with her size. She hates that she is short. It doesn't help that her sister is taller than average!! We work hard with both about the fact that kids have different gifts. Unfortunately, the younger one feels very inferior to the big one because older sister is very outgoing, has loads of friends, etc. Finding out that peer relationships may be affected when a child is gifted has helped us to understand some of the little one's issues with friendships!! I hadn't thought about the fact that younger sister might impact older one's social life. Something to think about for sure.
