Your nearest Calmbirth practitioner could take you through a few things separate to the course, as the course doesn't happen till you are quite a bit more pregnant.
My HypnoBirthing practitioner (training for Calmbirth now) had another modality up her sleeve called Emotional Freedom Technique (EFT), and I found she really helped ease my worries about impending parenthood, when I thought I wasn't parent-material. The Natural Therapy Pages on the web will have a listing of practitioner near you who do EFT
I'm going to have to do my own bit of counselling, I think, because as much as our next one is planned and wanted, I'm very conflicted about how to fit in a new person when I'm so involved with DS and really, really connected with him. I want to enjoy the pregnancy instead of pretending it's not happening to hope it all works out for the best!
