This article offers a rethinking of protection based on synthesised data from Finland and Sweden on children's and mothers' experiences of post-separation stalking, and social workers' case reports on children risking exposure to gender-based violence after separation. Drawing on critical childhood studies and a feminist approach to violence and security, we ask how children's everyday lives can be incorporated in a rethinking of protection for children in post-separation contexts. Departing from identified limitations in protective solutions for children, we propose three ways of rethinking the issue of protection: (1) protection as gender- and power sensitivity, (2) protection as securitising the here and now, and (3) protection as social peace. Our findings call for some changes in professional practices, social policy and legislation.
