Your doula can stand in a combination of roles depending on your individual needs.  Some couples will need an advocate.  Many moms and dads appreciate that someone familiar with their birth expectations is there to encourage and remind them of their goals.

In some situations, couples feel pressured to make hasty decisions.  A doula can relieve that pressure by giving them the opportunity to consider all their options.  She can make suggestions or inform them of their alternatives.

Doulas do not take over the role of the primary support person unless specifically asked to do so.  In fact, many fathers like the idea of getting the support for themselves.  A doula can give dad a lunch or nap break or provide the little tasks that might otherwise keep the partner away from the labouring woman.  Taking pictures, fetching hot packs or cold drinks are some of the many overlooked little duties of the doula.  Often an inexperienced labour support person will fear forgetting everything he or she learned in preparation classes.  Your doula can serve as a safety net also.

The physical support a woman receives from her doula is especially beneficial.  This is often true in case of back labour.  The doula is trained to comfort the labouring woman through massage and a variety of other non-invasive methods.  Moms usually need physical support during pushing, freeing dad up to view the birth.  The doula will continue giving firm, gentle commands throughout labour and delivery, often staying on until after recovery.

The emotional support received is valuable in giving mom confidence and reassurance.  Positive verbal comments or even a hug after a tough contraction are important to her state of mind.

Because the doula is not present to rescue her from her pain, she is not as emotionally attached as the father.  This allows her the ability to evaluate situations from a clearer perspective.
