In the Netherlands it is very common that you are at a midwive practice with multiple midwives. When birth starts, you have no idea at forhand who is going to support you.
When you have a medical indication, you are giving birth in a hospital. Than you really don't know who is going to support you. And every 8 hours there is a new team. So every time you have to gain trust in your new caretakers. Does this make you insecure?
A doula can be an answer if you want have continue support during your whole birth.
