We work to create a healthier and more equitable future for all pregnant, birthing, postpartum, and parenting people and their children.


Since day one, we’ve been fighting to give mothers and children a healthy first 1,000 days.

1,000 Days was born in 2010 in response to ground-breaking scientific evidence that identified a powerful window of opportunity from a woman’s pregnancy to a child’s 2nd birthday when nutrition has a long-term impact on the future health and development of both children and societies. We coined this window of opportunity the first 1,000 days.

With the backing of the U.S. Government, the Government of Ireland, the Bill & Melinda Gates Foundation and several nonprofit organizations, 1,000 Days began its work as a partnership to drive greater action and investment to improve nutrition for women and young children throughout the world. In 2015, our work expanded to focus on the issues that impact the nutrition and well-being of mothers, babies and toddlers in the U.S., particularly the most vulnerable. In 2020, we became an initiative of FHI Solutions, a subsidiary of FHI 360.

1,000 Days has developed an enduring narrative about why the first 1,000 days is a window of opportunity that matters for the futures of women, young children and their societies. Our work is inspired and informed by mothers in the U.S. and around the world who strive every day to give their children a strong start to life. And through the tireless efforts of a small but mighty team of passionate advocates (many of whom are mothers themselves), 1,000 Days, an initiative of FHI Solutions, has become a leading voice on the issues that affect babies, toddlers and the people that love them.
