My lovely daily nanny earns £330 net per week, to go up to £350 in January (though she doesn't know that yet...). This will be our first Christmas "together"; I don't want to embarrass anyone; what would be the going rate for a bonuc or Christmas present? I figure cash may be most appreciated; is £100 too little? £150? £150 plus a bottle of bubbly??? Advice anyone??? Thanks!
