World Breastfeeding Day 2026 is being observed from August 1 to 7 with the theme “Breastfeeding for a sustainable start in life: strengthen what works.” The week-long event emphasizes the importance of monitoring progress, assessing the impact of current initiatives, and expanding proven strategies to enhance breastfeeding outcomes globally.

The observance traces back to a 2018 resolution by the World Health Assembly, which recognized World Breastfeeding Week as a vital health promotion tool. Each year, the campaign highlights a distinct theme aimed at fostering supportive environments for breastfeeding. This includes backing from communities and workplaces, as well as protections embedded in government policies and legislation. Information dissemination about breastfeeding benefits and effective practices also forms a core part of the effort.

The 2026 campaign urges governments, health care systems, employers, civil society groups, and families to build upon successful experiences by reinforcing the “Warm Chain of Support” for breastfeeding mothers. In Iran, the Ministry of Health is conducting activities nationwide throughout the week, with each day dedicated to specific topics related to breastfeeding. These include the right to health for mothers and children, breastfeeding during crises and conflicts, youth involvement, baby-friendly healthcare centers, social responsibility in workplaces, supportive policies and laws, and dignity-centered approaches to investing in future health.

Breastfeeding is recognized as one of the most effective methods to promote child health and survival. Despite this, global data indicate that fewer than half of infants younger than six months are exclusively breastfed, falling short of World Health Organization (WHO) recommendations.

Breastmilk is widely regarded as the optimal source of nutrition for infants. It is safe, hygienic, and rich in antibodies that protect against common childhood illnesses. It provides all necessary energy and nutrients for the first six months, and continues to supply up to half or more of a child’s nutritional requirements throughout the remainder of the first year, and about one-third in the second year.

Research also shows that breastfed children tend to achieve higher intelligence test scores and face lower risks of obesity and diabetes later in life. For women, breastfeeding is associated with decreased risks of breast and ovarian cancers.

However, global efforts to increase breastfeeding rates face challenges, notably due to the inappropriate marketing of breast-milk substitutes. Such practices undermine initiatives aimed at improving both the prevalence and duration of breastfeeding worldwide.
