--- - |2 Abstract This first special issue dedicated to grandparenting patterns and their significance within transnational families sheds new light on transnational grandparenting as a phenomenon reflecting the convergence of three major transformations in today's societies – global ageing, diversification of migration and mobility flows, and lifestyle individualization. It contains five articles based on empirical studies conducted in several European countries (Switzerland, Luxembourg, Spain, Romania, and the Czech Republic) focusing on transnational families from both boh EU and non‐EU countries (Germany, France, Italy, Brazil, Morocco, Algeria, Switzerland, Britain, Portugal, Romania, and Vietnam). These articles portray transnational grandparenting through the prism of three nexuses (mobile/non‐mobile, migrant/non‐migrant, and kin/non‐kin), thus allowing one to understand grandparents' roles in the transnational circulation of care in the light of contemporary family transformations on the one hand, and of the increased transnationalization of everyday ‘doing family’ practices on the other. - 'Global Networks, EarlyView.
