I personally would choose somewhere in southern EU like Portugal, Spain, or Italy. Better weather and I think lower cost of living - assuming her salary is same in any EU country and they aren't pro-rating it.

You will most likely have to supplement any education for your child anyhow (to educate them on English and American things), I wouldn't focus too much on that being a deciding factor. As much as there are different areas in the US, the culture is very similar. I imagine being a road trip away from the language and culture of another country will provide more perspective and opportunities for education than you could get here in the US.

Maybe the company can offer up ex-pats in your top 3 countries that she can talk to for an idea on what its like?
