DS1 starts pre-primary/prep/foundation next year. We are in WA at the moment, but there's a good chance we'll be back in Qld by then...not sure how the change will go. Either way, the education system seems similar between the two, and DS will be one of the youngest. Academically, I have no qualms about his readiness. Socially and emotionally he's made great progress in the last six months, partly from going to 3yo kindy, so I'm hoping he'll continue to mature over the next 12 months. If it's too much, he'll do kindy again next year.
