If you want some ideas here are a few:
Montessori in early education (our chosen children’s nursery between 1 and 3 years old is a Montessori one);
Steiner system (we have been considering this option if our son does not get into a primary school of our preference);
Bilingual schools (such as French, German or Italian, though I am not sure about the existence of other languages… Usually private so you need to consider if affordable for your household).
For once, I have just thrown some suggestions out there, I will let you study your options more into details by yourselves 😉
