In the years after Radić published his work, the number of rhetorical works increased. They continued to be published in the Annals of the Life of the People and Customs of Southern Slavs. According to that, numerous number of monographs were produced and they are still representative today. Children's folklore is not often treated as a separate area of research. The systematicity of the recorded material depends on the author. Recorders of nursery rhymes are concentrated on the text, on the stringing of incoherent words, so in that way nursery rhymes are connected with the area of the irrational. Attention is paid to the textual features and basic characteristics of that literary form. Nursery rhyme is a true reflection of children's way of life, children's free play and imagination. Child spontaneously and dynamically creates nursery rhymes. Adults have often had the wrong approach in studying of nursery rhymes. They expect a meaning that really shouldn't be there. The child considers the word as a sound phenomenon and then it is used in sound games and counting out nursery rhymes. We can see that nursery rhymes belong to the all age periods, more than other rhetorical forms. But only the most recent studies of nursery rhymes have revealed the magical world in them.
