We're a roaming family. DP and DS (3) are Dutch, I'm from New Zealand (technically) and DD (grown) is Australian but pretty happy to live anywhere in the world.
Compulsory school age in the Netherlands is 5 years and most kids are in preschool at 4, with nursery/creche etc pretty popular too at 3 and under. We're in Portugal right now and will be moving here eventually. But as our income is portable we're free to have a homebase in Portugal and ramble about the world within certain constraints.
Compulsory school age here in Portugal is from 6 years, with preschool being both free and completely without a set timetable. As long as you let them know when you'll be using it you can basically drop in and out as you need to.
We have also been considering Home Ed. Or a combination of school and Home Ed which is well-known in the UK but almost unheard of in the rest of the EU.
I know every child is different but I'm interested in your experiences: What is, or what would have been (in hindsight) the ideal age for your DCs to start school/preschool? Or would you have avoided school altogether?
We're extremely fortunate to have so many options but it also makes choosing the right path really difficult. Help!
