Tansy, yes, she does work very hard - the second series showed them doing the food and the weddings must be a huge amount of work for her - 2 small children to raise too, it must be full on, even with some paid help.
it was funny when she said to the little girl ' did you speak any French?' and she just said 'no' - typical kids, they never tell you what they did at school or nursery! Their zest for life is amazing though, they seem so at one with it all.
