I'm sure one of the practitioners or other HypnoBirthing couples will be along shortly to answer this but I thought I'd offer a comment.
It was my wife Jenny who taught the couple featured on Richard and Judy, and Steve was very sceptical when he first came to the classes.
Many of the husbands come along with a very sceptical attitude but they often end up the most evangelical about it in the end.
On a more practical note, whoever attends the classes with you really needs to attend the birth too. The techniques are taught to you both, and the support of your birthing partner, whoever that happens to be, is very important to your success.
We have had women do it alone successfully but you really want to be able to relax and have someone there to support you who knows and understands what you are trying to do.
As for classes in the Yorkshire area, I presume you have filled in
this form on the website?
The HypnoBirthing Institute in the US holds the master list of practitioners - hence our needing to channel all enquiries through them.
Hope that helps
Best regards
Gordon
