High and Increased Positive Public Opinions About Supports for Breastfeeding, United States, 2015-2024.

Because breastfeeding behaviors are influenced by social norms, we examined public opinions toward societal supports for breastfeeding using data from the 2015 and 2024 SummerStyles surveys (N = 4127 and N = 4371, respectively, from the noninstitutionalized US population). In 2024, 81.9% of respondents agreed "there should be paid maternity leave for workers," 73.5% believed "women should have the right to breastfeed in public places," 66.9% agreed "women should be encouraged to breastfeed," and 65.9% agreed "a mother needs a lot of support to breastfeed her baby"-up 12, 11, 5, and 17 percentage points, respectively, from 2015. High and increased positive public opinions about supports for breastfeeding suggest heightened approval for breastfeeding-supportive programs and policies.
