The First 1,000 Days approach highlights the time between conception and a child’s second birthday as a critical period where adequate nutrition is essential for adequate development and growth throughout the child’s life and potentially onto their own offspring. Based on a review of relevant literature, this commentary explores the First 1,000 Days approach with a maternal lens. While the primary objective of the First 1,000 Days approach to nutrition is to reduce child malnutrition rates, particularly chronic undernutrition in the form of stunting, interventions are facilitated through mothers in terms of promoting healthy behaviours such as exclusive breast-feeding and attention to her nutritional status during pregnancy and lactation. Though these interventions were facilitated through women, women’s health indicators are rarely tracked and measured, which we argue represents a missed opportunity to strengthen the evidence base for associations between maternal nutrition and women’s health outcomes. Limited evidence on the effects of dietary interventions with pregnant and lactating mothers on women’s health outcomes hinders advocacy efforts, which then contributes to lower prioritisation and less research.
