I have just had a quick chat with my daughter's nanny who is going to be crucial to helping us get her trained. Do you think I can ask her not to use the word 'toilet'? I am from the US but I am conscious of the whole class issue around 'toilet/loo' and don't want to offend her!! But I have to say I am now not crazy about the word myself. I say 'ladies room' which sounds unbelieveably victorian and my daughter would undoubtedly get laughed at when she goes to preschool if she does the same! I probably get away with it due to the American accent.
I was just going to suggest 'bathroom' instead of toilet but don't want to offend her either - maybe I shouldn't bring it up at all?!
