The Justice for Incarcerated Moms Act provides funding to promote exemplary care for pregnant and postpartum people who are incarcerated jails to establish programs for pregnant and postpartum women in their facilities, including access to support for doulas and other perinatal health workers, counseling, reentry assistance, maternal-infant bonding opportunities, and diversionary programs to prevent incarceration for pregnant and postpartum people. The bill also commissions a comprehensive study to understand the scope of the maternal health crisis among incarcerated people and to make recommendations to prevent maternal mortality and severe maternal morbidity in American prisons and jails. Finally, the bill ties federal funding for state and local prisons and jails to prohibitions on the use of restraints for incarcerated pregnant people to end the practice of shackling.
