If you have enough money, Switzerland is great! Being able to shrug off Unexpected costs and not flinching when you receive another grey enveloppe, has advantages!
In my experience, people who are happy to make the move and embrace the adventure, settle most easily. I met one woman who came, and left.. she said 'The Swiss are relaxed about nothing' and she really hated it.. so moved back on her own with her children.
The population density of Switzerland is much lower than England, the greater Zurich has a population of 2m compared to London's 9m.. which results in something feeling 'Swiss'... nice, well organised and sometimes underwhelming.. but I love this!!!
I know a few families who came here expecting to feel rich, but to find that they are not as rich as they were in London, Copenhagen or elsewhere.
I would also say that international schools are unlikely to come up to the standards of similar priced schools in London. That said, my kids have been very happy going through international school.
Yes, there are rules, traditions, somethings that feel old fashioned, people will tell you when have done something wrong... but these are also some of the best things about Switzerland.
There are lots of foreigners and if your husband is Swiss, you will find it easier to make local connections.
For young children, I feel that there are fewer organised activities, families tend to do things together and at home, rather than the huge selection of activities available elsewhere.
