PURPOSE: to analyze the report of the families on the development of their monozygotic twins since the acknowledge of twin pregnancy, and describe the environmental factors, as well as their relationship with language. METHODS: the study is based on naturalist/observational approach and the data were collected through semi structured interviews with nine families who had a pair of monozygotic twins, during thirty months. Data analysis was performed by using historic-cultural perspective and indicative paradigm. RESULTS: seven families described a differentiated language development, but it was not stressed out in such a relevant manner to the point of causing concern to these families. CONCLUSION: twinning may bring out the idea that the development of these children do not follow the expected, once that twin children are also not expected.
