There is some evidence that Early Childhood Care and Development (ECCD) has increased women's workforce participation. The majority of the literature on ECCD comes from an education viewpoint and is child-focussed. It notes that parent or family carers are more able to work or study due to childcare programmes. The point generally seems presumed and further explicit evidence or explanation is not given.
