Our Affiliations
The Birthing Center at Holyoke Medical Center

From big decisions (How do I want to manage pain or discomfort during labor?) to specific details (Please provide a hand mirror so I can view the birth of my baby) you create the birth plan that works for you. Services and choices appreciated most by our patients include:

  • Safe and innovative pain relief including nitrous oxide. We were the first in Massachusetts and also among the first in the U.S. to embrace a reliable pain management practice that provides the patient greater control.
  • “Skin-to-Skin” contact between mom and baby, directly after birth. A practice with proven benefits: easing a newborn’s transition to the outside world, regulates breathing, increases immunity, strengthens bonding and more.
  • Birthing Tub for those looking for a distinctive and comforting option to bring their baby into the world.

The Birthing Center was the first Baby-Friendly® hospital in the Pioneer Valley. The international award recognizes birth facilities that offer breastfeeding mothers the information, confidence and skills needed to successfully initiate and continue breastfeeding their babies.

Appointments available in Holyoke and Westfield. Call (413) 534-2826.
