JD has been seemingly unaffected by the switch, just enjoying seeing his old toys again and sleeping in his own bed. He also showed no signs of jet lag. I woke at 4am one morning but otherwise have been alright. JiaJia though has had a few days of going to sleep at 5am and finally waking at midday. She's never the best sleeper, but this time it's taking her longer to adjust to China time. She is already back at work. I have a further week's holiday, while JD has two weeks vacation left.
