If you saw the bit on the Today show about doulas it was not very complimentary. It referred to doulas as a luxury and said buyer beware. The only person they really interviewed was a doctor who has banned doulas from her hospital. They didn't interview anyone who had used a doula. They didn't talk about the benefits of doula support or the amount of work that goes into training and certifying. The article on their website was a little better. Please feel free to write to the Today show in support of what doulas do and the many benefits of doula support.
Here is the link to the article on their site.
