Yeah, our school is doing the same thing - older kids will go back on the 30th and DS2 will have his best start on the 31st and then start school on the 1st. Works out well because we have to take DS1 to his school on the 30th too, so we can get the girls on the bus and then take him to his school. I was really worried that both DS's would have to start school on the same day.
