This is not the description you usually find on the web for doula bag supplies. But in reality the most important "thing" that I bring to your birth is me! I use makeshift things for counter pressure. Last time I used a bottle of water. Which was great because I could alternate hot and cold with water as the mom requested. I've also made a rebozo out of a spare hospital gown. If I see a mom uncomfortable in her position, I'm going to help find a better position, even if confined to a hospital bed, I will help her find the best relief and/or ask the hospital staff for a happy compromise. ie, standing next to the bed. During a long labor at home, I do a lot of cooking. And I'm not just cooking anything, I'm thinking about what nutrition mom is going to need at the different stages of labor. Then I wash the dishes. For massage, I prefer to use your oils and lotions to save us the possibility of you having a bad reaction to something I may have.
While I cannot speak on your behalf to medical staff, I can run interference with family. I can hug grandmas and give them reassurance. I can usher the uninvited cousin who found out about the birth, out of the room. I can run to the store and get that thing you forgot.
For dads/partners, they can relax and have someone else to lean on. I let mom's know I am here to take care of the three of you so mom can concentrate on her birth. I will send dad to shower, eat and take a 20 min nap when needed. I'm also going to encourage some alone time just the two of you to give you both a chance to savor the moment in private. For a mom who needs a lot of physical support, I can show dad exactly how to use his hands and body to help her cope.
Most importantly I am holding space. From our prenatal meetings I have gotten to know your family and understand the birth you desire. While I cannot guarantee the details, I am your support person to help you stay empowered. I am the person who can remind you of your birth plan, and who will support you whatever you decide. I am at your service. I will be calm and strong for you, and help you find the calm and strength within yourself.
