Pam, I'm the other way round: White British married to mainland Chinese man. We have several (can think of 6) pairs of friends who are the same, which we tend to put down to the fact that more women studied languages including Chinese, then we all went to China to work/study, in our twenties, and all met lovely men there!
Twiglette my Scottish Mum and Dh's Chinese Mum met for the first time this year, even tho we have been married since 1987! It was only for 2 days and they have no language in common so they didnt get past the polite chit chat stage. But from what they said to us, separately, I'm quite glad it just stayed superficial and friendly. The gulf between them is just so huge, in practically everying. (except for love of the grandchildren, but even that is expressed very differently)
I havent been on here for ages, SO busy, that I only ever get a quick snatch of Mumsnet and no time to get involved in any 'conversations'. I'm at work now...We are having building work at home, plus just always busy with three children, it's non-stop.
Congratulations to all new Mums and babies!
