Hi LKC, thanks for answering my post.
My son will be going back to the school he left in the UK so I think holding him back a year when all his old mates (who he's still in touch with) will be in the year above would have a massive effect on his confidence / behaviour and everything. So that's not really an option. I think that would cause more stress than anything else.
My gut tells me I should insist he goes up to Year 3 in Aus but the school isn't really up for it, I'd have to push for it. But then I also think that it'll be more upheaval for him to move classes again. So, if husband is right, maybe I am stressing out a bit too much over this. He's only young, he's bright and socially confident....perhaps he'd just need a bit of extra tutoring....I just don't know what to do for the best.
We're moving back to South East England. x
