I'm a new lecturer and this September will be at a conference in Germany for a week before 1 day at home and then 2.5 weeks teaching in China. I also have 4 year old twin boys who will have started school just the week before I leave. I've been away from them before but only for up to a week. Any tips on how to prepare them? Should I see them for the one day in the UK or will this just disrupt things more?
