M.,
My sister-in-law and her family moved to France from MI on very short notice last summer. Their children were 8, 6 and 2 at the time. Her husband still travels a lot even now that they are living in Paris.
I can tell you the positive and negatives and am happy to offer you her feedback directly if you'd like to exchange emails with her.
She is a very laid back and patient person. There has been a lot of getting used to the European way--the basics of shopping, knowing store hours, getting around with public transportation (they do have a car but parking is tough) finding ingredients, figuring out the school system, etc. is challenging.
Her kids are having a fabulous experience and she was worried how her son would adapt but he's doing great. I imagine at least the youngest child will be bilingual and they send pix every few weeks of all the amazing countries they have visited. The youngest has adapted the most easily I think.
There was a lot of pre-planning to be done in order to have the right supplies while they were there--including food, clothing, toys. I know the prices for many things are quite astronomical in France and they had some items shipped by container and others they packed for the flight.
Their plan was to be there for 2 years and it looks like they might extend to 3 now.
Let me know if you want to contact her directly, I'm sure she'd be frank with you. Her husband is in the auto industry and they are honestly thankful they are in Europe with the state of that industry here in the US. They also knew some day he'd get an overseas assignment in order to keep moving up in the company and were thankful they got France as an option because it's got better living situations than some of the other countries.
