What are the school hours for your kids? In our district, all the schools are really split up- there's a separate school for just K-1, then another for 2nd-3rd, one for 4-6, etc. And it seems like each school has slightly different start and end times. I guess it's so the bus transportation can accomdate all the kids. It does make it difficult though when you have more than one child - it seems like every other year (and sometimes every year), we have to adjust to a new schedule. Right now, my youngest son school starts first but next year I think it will be my older son's.
Just curious how it is in other parts of the country :)
