Absolutley.  Choosing effective childbirth education increases one's knowledge and confidence about the birth process.  The more knowledgeable you are about birth the calmer you will be in labor and you will be able to make educated decisions along the way.  Your doula will offer informational and emotional support before labor begins and will offer comprehensive support during labor and birth.  However, only you can labor and birth your baby, and the more prepared you are for that task the more empowering it will be.
