Key Social Norms Take-aways This study highlights how social norms around marriage, fertility, and womanhood shape postpartum family planning in urban Yogyakarta. There was a strong expectation that women should become pregnant soon after marriage, particularly among those who married in their late twenties or thirties. These norms often overrode women’s personal desires to delay pregnancy and limited their reproductive agency. Norms also framed family planning as something appropriate only after having children, reinforcing delayed engagement with contraception. Family size ideals—especially the desire for a “complete family” with one son and one daughter—were widespread. Women’s choices were often influenced by peers and family members, leading to misinformation and limited contraceptive options. Provider attitudes, especially in the public sector, sometimes restricted informed choice, further constraining women’s ability to make autonomous decisions. Collectively, these norms reveal the relational and embedded nature of reproductive decision-making in Indonesia.

Objectives To explore how middle-class postpartum women in urban Yogyakarta, Indonesia understand and make decisions about family planning, including the influence of societal norms, interpersonal relationships, and health system interactions on their reproductive agency.

Methods This ethnographic study drew on 31 in-depth interviews with 20 postpartum women aged 21–38, conducted between April 2015 and March 2016 in urban Yogyakarta, Indonesia. Participants were selected using a multi-stage non-probability sampling approach. Data collection was iterative and incorporated participant observation, semi-structured interviews, and focus group discussions. The analysis focused on identifying themes related to women’s family planning knowledge, decision-making, and reproductive agency within their social and relational contexts.

Results Participants commonly viewed pregnancy soon after marriage as expected, especially for women marrying in their late twenties or thirties. Biomedical contraception was seen as inappropriate for women without children, and none used it before their first pregnancy. While a few successfully delayed pregnancy using natural methods, many lacked the ability to negotiate postponement. After childbirth, contraceptive choices varied: some began immediately, while others waited for menstruation to resume. Most women had limited knowledge of available methods, including the lactational amenorrhea method, and often relied on natural methods due to misinformation or cultural beliefs. The ideal family size was two or three children, often with one of each sex, but husbands’ preferences sometimes conflicted with women’s. Access to postpartum family planning was uneven: women using public services described provider coercion or misinformation, while private providers were more likely to support informed decision-making. Peer and family influence played a major role in shaping choices, sometimes enabling, but often limiting, reproductive agency.

Conclusions Women’s reproductive agency is constrained by societal expectations, limited contraceptive knowledge, and inconsistent provider practices. Enhancing access to comprehensive, early family planning education and improving provider communication—especially in the public sector—are critical to supporting informed reproductive decisions and improving maternal health outcomes.
