I am okay with some of the sibling rivalry. As one article I found pointed out, the only way you have zero rivalry is if one kid is running the other kids. I know that has happened at times. (Although, in truth, they take turns running each other, so maybe it isn't completely unhealthy.)
As for summer school, we do have the tutor one day a week - but the kids consider that fun rather than educational, and I think she runs it that way. Just that she runs it as fun for really smart kids, so there is some intellectual stimulation there.
Snoopy is still doing ALEKS over the summer and I have given him a goal of wrapping up the 6th grade material. Granted, it isn't a very ambitious goal given where he is now, but a goal nonetheless.
As for Barbie, she is a reader and is challenging herself well.
OT - does anyone have a good source for titles that are appropriate for an 8 yo who reads like an adult?
