What exactly is a Silent Birth?

This is all about providing the best possible environment for the birthing mother and her new baby.

Silent births are labor and delivery done in a calm and loving environment. This means everyone attending the birth should refrain from spoken words as much as possible. Chatty doctors and nurses, shouts to “PUSH, PUSH” and loud or laughing remarks to husbands are the types of noises that are meant to be avoided.

The idea of silent birth is based on L. Ron Hubbard’s research into the mind and spirit. He found that words spoken during moments of pain and unconsciousness can have adverse effects on an individual later in life. What has been said during traumatic experiences such as birth records in a part of the mind called the reactive mind. These recordings store and have the power to influence a person by dictating thoughts, emotions and psychosomatic ills not under his control. Anyone can read about this in the book Dianetics: The Modern Science of Mental Health.

Mothers naturally want to give their baby the best possible start in life and thus keep the birth as quiet as possible
Nothing about that resembles all the hype in the media about TomKat when Katie was pg.
To me this is just the same as Hypno Birthing.
Although im not sure if I agree with the part that says What has been said during traumatic experiences such as birth. Im not sure if they mean birth is traumatic over all or just when there are reasons that may make the experience a traumatic one. I woudn't have thought the birth process to be a traumatic one for mother or baby if all goes well KWIM? But Im not sure exactly what they mean by it so I could be way off & they do only mean in regards to a birth that is not normal.

What goes on at a silent birth?
There is no specific routine. Just like care is taken in all other aspects of labor and birth, a woman and her doctor or midwife and any others present work out how to communicate without words. Different women have done different things.
Overall I take this as being "pro" a nice & calm environment for birth to take place. Nothing bad about that.
