This scientific work wanted to study the dialogically relation between a pair of children during a designed game, investigating how a child plays the interpreter's part, instead of the other child. There has been realized 5 video engravings at Creche Vila Prado with each pair of child-child. The children were Mara Rúbia (born in 22/01/89), Renato (born in 10/01/89), Vivian (born in 16/01/89) and Everton (born in 25/09/89). The video engravings has been done twice a month and they had 20 minutes of duration. After that, there has been done the "corpora" of each video engraving, to do analysis next. The analysis showed that, in the dialogically relation between child and child, the responsib ility of structuring and maintenance isn't placed in none of the children, but divided between them. However, this subject needs more studies. There're a lot of doubts about dialogocally relation between a pair of children, but the right point is that it's favorable to the development of the language.
