To get the maximum benefit from this CD, you should learn the techniques from the Natal Hypnotherapy birth preparation CD and the book during the last trimester of you pregnancy. This CD can then be used to reinforce the techniques during the birth. There are three hypnosis tracks which can be listened to at different stages of labour and these have been designed to reflect the emotional stages you are likely to go through. The reduce adrenaline track is particularly useful if you are disturbed during the later stages of labour.
