The term nursery rhyme is used for "traditional" songs for young children in Britain and many English speaking countries; but this usage dates only from the nineteenth century, and in North America the older Mother Goose rhyme is still often used.[6] The oldest children's songs of which we have records are lullabies, which can be found in every human culture.[7] The Roman nurses' lullaby, "Lalla, Lalla, Lalla, aut dormi, aut lacte", may be the oldest to survive.[7] Many medieval English verses associated with the birth of Jesus (including "Lullay, my liking, my dere son, my sweting") take the form of a lullabies and may be adaptations of contemporary lullabies.[8]
