Maternity protection policies aim to support working women and their babies, promote breastfeeding, and prevent discrimination. Advocates in Indonesia, Nigeria, the Philippines, and Vietnam have shown that successful advocacy for paid maternity leave and workplace lactation policies involves building strong partnerships, understanding the local context, and presenting these policies as part of a broader set of social protections. By working with diverse stakeholders and tailoring strategies to each country's needs, advocates can effectively push for reforms that benefit women and children in the workforce.
