The oral literary genres that children encounter in their earliest years include, besides counting rhymes, lullabies. Lullabies, by their characteristics, combine two forms of literature – children's literature and oral literature. Their primary function is to put the child to sleep, which is achieved through texts adapted for children and accompanying melodies. They are significant for the child's overall development, especially emotional development In addition to oral lyrical songs, there are songs that were not originally intended for lulling, but take on that function, such as counting rhymes, children's songs, etc. The language of lullabies does not necessarily have to be in the mother tongue; singing in a foreign language is becoming increasingly prevalent. This thesis analyzed the poetic characteristics of lullabies. The research consisted of two parts – an online survey and field research. The online survey examined who the most frequent narrators are, their singing experiences, and the times when they sing. The field research has shown the diversity of poetic characteristics in lullabies and the importance of collecting oral literary material.
