Our plan is to send our children to private school for senior years (7-13.) However, I’m not sure whether it might be best to see about moving them a bit earlier. As things stand, just about everyone at the primary school they will attend goes to the same (state) secondary and I can imagine it might be difficult for DC to go through Y6 and be going somewhere else, and potentially then start at a new school with established friendship groups.
There are two school years between our children.
