Some states such as mine do not require a special certification to label oneself as a doula. If you are in business for yourself, it is more of a preference.
We all have to grasp at straws to place blame with this kind of hurt happens. Blaming yourself won’t bring your baby back. Use this unfortunate event to become stronger and speak out. Most people think it’s rare, but in reality it isn’t. The more we speak the more they know. The more we know. Remember that pregnancy and infant loss isn’t your fault.
