Child-oriented researchers have long recognised children's right to be heard in research about their lives and, as experts about childhood, their perspectives should inform social policy and research. While it is encouraging that more children are consulted about matters of importance to them, some children's voices remain silenced. When researchers have to liaise with adults, such as parents and social workers, to recruit children, these adults make decisions about who participates. An account of recruiting children of mothers with intellectual disability, a potentially disadvantaged group, is presented. The reasons for gatekeeping and the implications of this are explored.
