I remember French also use many words (bobo, zizi, bébé, chou-chou) made by duplication in children's language. I wonder what words you remember, maybe there are some similar words. Don't copy my list of words feel free to add your new words. Thanks. father = papa mother = mama child = baba hurting spot on body = bibi to sleep = csicsikál (verb) faeces = kaka, kaki urine = pisi food = papi I can't remember more now.
