It's something to think about for sure!! They already deal with that as it's a magnet school, and they take electives together plus they have gotten the same teacher twice!! They go to Girl Scouts together and have wanted to be in the same activities in the summer. I plan on placing them in different activities this year if they will let me. I remember that my little sister came along 4 years after me, and she STILL complains that she was compared to me.
