For those who have used castor oil, how did you do it? Did you get the okay from your doctor first? I'm 40 weeks today and have been planning a water birth, but we have a two year old and my mom only planned a week long stay. She leaves on Sunday and still no baby. I need someone to take care of our son because my husband is my "support person" and he can't take care of my son or else I can't give birth at the birthing center. I'm freaking out. We don't have a lot of family and my mom can't stay longer because of her job. I'd love to hear castor oil stories.
