At the moment we have 1st August pencilled in, but it's a pretty arbitrary date. The dc's school finishes on 27th July and their new school will start on 1st September.
I can't decide whether the dc finishing school so close to the current move date is a good thing or a bad thing. It feels like it would be so rushed for them, and they'd be tired at the end of the school year, but it could also be useful for the last minute organising to have them at school.
There's also a balancing act at the other end - I've read that getting them into school soon after the move helps to get them settled and making friends, whereas with a month to ourselves in a new place without any structure could be hard. But could be good to give them some time to acclimatise without the added newness of a new school?
Dc are 7 and 5. DH will be able to take some time off before starting work whenever we go.
