  • Birth balls and balance bars to enhance mom’s labor progress
  • A fold-out couch for your birth partner.
  • Flat-screen TVs with an auxiliary jack for MP3 players and other electronic devices

  • Room service meals help you plan eating around your baby’s feeding schedule.
  • Breastfeeding support provided by your Mother Baby nurse and lactation consultants when needed. Our lactation consultants are on-site seven days a week, and outpatient lactation consults are also available after you and your baby are discharged.


Many expectant parents find comfort in knowing that if needed, Mercy Birthplace - South has a Level II Neonatal Intensive Care Unit ready to address any newborn-related health concerns.

Sleep Safety

Mercy Birthplace - South is a nationally certified Safe Sleep Hospital. We are committed to educating new parents and caregivers about safe sleep habits.

Wait ‘til you see what we’re building for you

In order to better serve the needs of families, Mercy Hospital South is rebuilding its entire labor and delivery unit. The improvements will include larger patient rooms, the latest technology and greater access to newborn services. Construction is currently underway on an approximately $17 million project, which is funded by the  Boniface Foundation.

Phase one in this 36,700-square-foot project includes a new entry space that greets everyone as the elevator doors open. Phase two will transform the east wing of the 4th floor, commonly referred to as postpartum, to create 15 Labor, Delivery, Recovery, Postpartum (LDRP) suites. These suites will be larger, providing a more comfortable space for a family’s entire stay. Two of the suites will have tubs, and the unit will also support low intervention births as well as moderate risk births. The new LDRP suites are scheduled to be open and serve families by the end of 2021.

Upon completion of phase two, construction crews will rebuild the west wing of the 4th floor, commonly referred to as labor and delivery. This side of the birthplace will include four flex rooms, three triage rooms, operating suites and a level two NICU with 24/7 Mercy Kids staffing. This phase of the project is scheduled for completion near the end of 2022.

Finally, the renovated east and west wings will be architecturally connected to the entry way, completing the entire project in early 2023
