"Can you support me if I want an epidural? I've heard that labour supporters (doulas) are only for ‘natural birth.'"
Of course we support you if you decide on an epidural! You get our support no matter what;
there's no pressure for you to follow any agenda for how your birth should be. This is your birth, and only you know what's right for you!
What's more, if you choose an epidural, your doula can help you with strategies to maximize the benefits and minimize the side-effects epidurals can cause.
