Are these sort of 'universal', or do babies make different sorts of sounds in different languages? I know that where in English we say a baby 'coos', in French a baby says 'Areuh' (sp?). We've been speaking French to our baby and he did, bizarrely, start out by saying 'Areuh'. Now he also says 'Egeuh' and 'Abuh' and has started singing 'Hou, hou' to himself (with a look of intense concentration), which is particularly un-French as they don't say H. NB he is 6 months old, in case anyone thought he was a retarded 7yr old!
