"....it's just me..."
The parent has to count in this equation too love.
Lots of parents cope with poor standards in some Italian schools (both Italians and expats) without wibbling all over the shop till the director of the school hides in his office when he hears the familiar clip clop of stilettos and a British accent muttering to itself all the way up the stairs. Again.
It was beyond my comfort zone and despite doing my level best to transmogrify myself into somebody who could cope with it sans Mount Etna like explosions all over my husband yelling ?your bloody country?? in my frustration... I didn't manage to have a personality transplant.
So I got counted into the factors to consider when we were working out what the hell to do with the situation we had to deal with, to give our chosen solution the best chance of success. Our son was in pole postion, but my feelings were a long way from being an irrelevance.
If you find yourself ever more unhappy with his experience at school, despite looking for ways to minimize both how it impacts you (and by extension him), then I don't see how that can't be taken into account when weighing up your options.
We are mums, not robots who gave up all personality, passions, foibles and hot spots when we gave birth.
You are talking about maybe HEing him, not handing him over to be raised by wolves. It is a perfectly reasonable choice among many perfectly reasonable choices and the best fit education wise tends to take into account the parent(s) AND the kid in combination, since both are involved.
Which is why I don't think the home ed is THE cure all for all educational ills, because if a parent has serious misgivings about it, no matter what might work for the kid in theory, it is unlikely to be a stellar experience for either of them and unlikely to be ?better? than all the alternatives.
You have a wonderful trip ahead of you and a great opportunity for both of you to ?suck it and see? when it comes to HE, once you are back you might find that one way or the other (or even another with a third option like flexi schooling) you have a clearer idea of what will work for both of you in practice, at least for the time being.
All we can do is make the child the central concern and bear in mind the reality of who we are when working out which way to jump when making our choices, to ensure that the solution has ?stickability?. That goes for all aspects of parenthood, so obviously it includes education too.
You obviously love your son to bits and have a clear vision of what issues are yours and what issues are his, without the need to transfer yours onto him to make it easy to ignore his perspective. That means whatever you decide he has the most important building block any kid needs, a parent who makes him the priority.
I?m sure you?ll do just fine at working out what to do and following though to the best of your ability with the above as a foundation.
