Well I wanted my baby to be born on the 29th of February (leap year) so bad I tried taking 1 tablespoon of castor oil with fresh pineapples. 4 hrs later, I went into labor at 38 weeks and 4 days. She was 6 lbs 4 oz, and healthy. Not only did I want her to be born that day, but everything became more difficult for me during my pregnancy, and I couldn't keep up with my daily activities. I was expecting my mom this weekend so I was anxious to make sure I could prepare for her visit before she arrived, which was also complicated for me to do while I was pregnant. If you ever think about taking castor oil to induce your labor, you have to make sure that you are already dilated.
