Shaking up Birth Order...?

If they are in the same grade, they should probably be in seperate classrooms. That allows them some individual time to be away from their siblings, and also decreases competitiveness a bit, as if they are in the same class, doing the same test, and one scores an A and the other an F, that can cause jealous issues, etc. But believe me, they'll find plenty of other things to be jealous over, compete over, etc!I have two kids going into 9th grade, and two going into 4th grade. The older ones stay away from each other at school, have separate friends, etc. The younger two are still young enough that they want to play together at recess, etc. It will sure help on graduation parties, though! LOL!!!As for birth order, I've never had any trouble with bringing in mixed ages as long as the oldest stays the oldest. Good luck!!!
