Quoting NRPS21:" Eh, most people smurf while giving birth anyways.. I am planning on asking about it at my next appointment. ... [snip!] ... I would go early so I didnt worry about it but it will definately matter to me if we're talking about an induction! Ugh."
No, not most people. It's something that CAN happen. Yes, baby can pass Meconium also. I've never heard of Castor Oil used on the stomach, that's new to me. But, if you're only taking a small amount of it orally, all it's going to do is make you smurf. It won't induce you.
Like I said, if you really want to try it, ask your Doctor. It should only be done under their supervision. Don't ever rely on what a friend/family member etc. says was ok for them.
