I generally believe babies come when they are ready. Any induction can cause complications you can't forsee, and may not want.
I'm sorry this MW gave voice to whatever niggling fears you may have already had.
You know your body best, and if you don't feel that inducing is worth the risks then leave it alone.
I, however have used a castor oil induction. No complications (other then cramps worse then contractions and worrying if you could die from pooping too much
) I know see that I was acting out of frustration and selfishness and my baby really could have used a few more days (weeks) on the inside. I was weak though, and didn't think I could bear it. But, whats done is done and I can't say that I wouldn't do the same again, were I ever in a similar situation
. still had a beautiful, quick, clean UC and bouncing baby boy in under 1.5hrs.
It's up to you, mama. YOu know your body, baby best. JUst don't act out of fear or uncertainty...or because of what one MW said (based on her own fear and loss of control).
Any time you induce you are interfering with the process. Birth is normally a dance between homones and cell messages so complicated that humans still can't identify the whys and whens or even draw a map of anything other then the biggest functioning of the process (the baby comming out, which muscles are working etc). The risk is throwing something artifical into a mix we can't even fully understand.
IMO though, castor oil is a jumpstart and soon out of the system. there are worse ways to induce. it's awfully painful, and it doesn't always work. You'll have to weigh the risks and benefits yourself, but I hope I've added a little for you to think over.
