When Denise Stern’s twins were born in 2009, she was ordered on bedrest due to serious medical complications. With 2 newborns, a 17 month old and a husband without paternity leave, Stern personally saw the need for qualified overnight newborn care and started Let Mommy Sleep. With a background in small business and a team dedicated to uncompromising standards, Let Mommy Sleep bootstrapped it's way into becoming the country’s largest team of Night Nurses and Postpartum Caregivers, with locations in 12 cities and franchising nationwide.

After experiencing the incredibly positive impact postpartum care had on the health of families, Stern launched the 501c3 non-profit, Mission: Sleep in 2012. The charity delivers free overnight care to military and first-responder families whose newborns arrive when a parent is deployed, wounded, or deceased.

The small business and non-profit began to receive acclaim and recognition from government and private sectors as well as the media:

- US Chamber featured woman owned business (2013)
- Mission: Sleep receives formal support from then Gov. Tim Kaine (D-VA)
- The only postpartum care providers to attend the White House Summit for Working Families, hosted by President Obama (2014)
- Awarded a government contract to teach newborn and postpartum care in Virginia (2014-current). This curriculum is used by pediatricians and organizations throughout the country.
- Washington FAMILY Magazine Mother of the Year in 2016
- partnership with INOVA Health in 2017, serving the 200 companies associated with INOVA.
- Lobbied Congressional Reps for better postpartum care in 2018 and 2019
- named a "Big Idea that Might Change the World" in Medium Magazine 2019
- contributors to major media outlets such as the Washington Post, NPR, FOXNews, Associated Press, Harvard Business Review, Slate and more.

The ultimate goal of Let Mommy Sleep is to revolutionize postpartum care in America, making it a national norm and aggregating a currently unregulated industry to fight for better maternal health outcomes -especially for women of color who are 5 times as likely to die during or in the year after giving birth. Immediate postpartum care has been proven time and time again to lower hospital readmissions and positively affect families for years to come, and Let Mommy Sleep can be the tool to help make those profound changes happen.
