I had no support from my family, not even my DH.
My OB was totally supportive, though. I hired a wonderful doula and went ahead with my plans for a natural birth. I listened to my birth hypnosis CDs, did lots of visualizations and positive affirmations, and practiced yoga. Once I went into labor "spontaneously" (with the help of EPO, RRL tea, lots of exercise & nipple stim and orgasms), DH became very supportive. My preparation really paid off, I had a long labor
with a posterior baby.
It's your body and your baby. Plan for the birth you want!
