I was in tears through most of the programme as I moved to France when I was 10 (for 4 years) with my parents & younger sis, so this brought it all back to me. My parents spoke a little French, me & sis spoke none! My parents decided it would be best (??!)to put us staight into french school. It was terrifying & an awful experience although my father still thinks he really enriched our lives by moving there (he decided we should move for financial reasons - long story!) but I can truthfully say that it didn't and it had a major effect on my emotional, social & psychological development. Although I do have to say that after about a year I was fully fluent in french and was top of the french language class which really pi*d off the other kids!
Personally I could never do that to my child, not unless they were really, really young.
Anyway back to the prog, just wanted to hit the parents, they were so arrogant believing they'd get by without speaking french and the dad was a right wet blanket!! And the way the mum was with the kids at school, especially Joe, she just seemed cold & inconvenienced!
Personally I could never put my own children through the experience, although I suppose it wouldn't be too bad to move with young babies.
