How to hire the doula for you
A doula can greatly enhance your experience of childbirth and the postpartum months. Your birth doula will be at your side along with your care provider and partner, as part of your team for continuous support during labor and birth. Or maybe you’d like a postpartum doula to help you through the transition into parenthood and family. Either way, finding a good fit for you and your family is critical.
A doula’s education, training, experience and credentials are important. When doulas have DONA International certification, you know that they have had the best education and training available. You can also be assured that they have a strong sense of professionalism and integrity.
You will also want to consider whether you and your partner feel comfortable with an individual doula. You will need to feel that this doula is supportive of your hopes and expectations about labor, childbirth and parenting, in addition to having a strong professional background and credentials. That is why we recommend the following four-step hiring process when hiring a birth or postpartum doula.
