[Experimenting curing-caring experimenting. Notes to prevent confusion].

Children, as well as adults, can be subjects of clinical trials. An overview of the history and development of clinical experimentation through the main scientific publications is briefly outlined. A chart of children rights is also presented and discussed. Children's rights range from the right of being included in clinical trials to the right of being participants in a research that complies, without being overwhelmed, with formal rules. The maximum respect for the child is assumed if innovative questions are asked and independence and autonomy of judgement of researches are observed.
