Early childhood research often involves direct work with children, their parents, families, carers and educators. The researcher has to ensure that all of these have given informed consent to the research, and that a protocol has been devised to cope with any sensitive issues that may arise. From a children┐s rights perspective, this is particularly problematic in the case of younger children and those who for any reason are not fully able to comprehend the implications of consenting to participate. This paper discusses some difficulties about ethical issues that have arisen in practice and identifies some issues of concern. The paper concludes by advocating the development of a code of ethical practice specific to early years research.
