Mama Bamba highly recommends that you also invest in post course supervision, which you pay directly to the supervisors, who accompany you to births initially, and help you with onsite training, observations and guidance. Depending on how much time you contract to work together with them, this can range from between R500 – R2500. It is not a compulsory cost, but it is very helpful to new doulas to attend at least one birth with a supervisor.
