We have 4 kids, each around 2 years apart, and we are hoping to relocate to a different part of the country within the next few years as we've both hit a career ceiling in our current location, and we just aren't happy here.
Our oldest 2 are very settled and we've decided it wouldn't be right to uproot them at least before the end of their GCSEs. There is no sixth form at their secondary so there's a potential window then, given that they'll be having a big change at that time too, but by then our youngest 2 (currently in the tail end of primary) will also be in secondary.
We get the impression the younger two will be more open to a big move (they have no memory of living anywhere else, and don't love it here, whereas the older two moved around a bit when they were young and got jaded by it, which is why we want that stability for them now). But if that's not the case by then, and we feel the younger two would be disadvantaged by a big move, then we will stay put until they're all through school.
However, if we do feel it would be ok for them to go sooner, then I can't figure out how we would go about making the move without completely disrupting their education? We'd have a child in college, one (probably) in uni, one thinking of GCSE choices, one just settling in, and so on. I should say this is state education, so at the mercy of local authority in year admissions processes. Has anyone made a big move before with kids in secondary & further education, and if so how did you physically make the transition with the schooling, and how did it all work?
