This article examines Norway’s child welfare service managers’ perceptions of infection control measures on service functionality. This longitudinal study entailed nine rounds of surveys (N = 153–214) with child welfare managers between April 2020 and September 2021, collected by the Norwegian Directorate for Children Youth and Family Affairs after the onset of the Norwegian lockdown of March 2020. The findings suggest links between the strictness of measures and ability of child welfare services to ensure appropriate service delivery. Lockdown caused significant difficulties for many municipalities, while milder measures had less impact. We discuss the implications for practice with children and families, concluding that addressing the community’s health needs during the pandemic also requires a consideration of the cumulative needs of families.
