A.,
Go with your own gut instinct! I don't want to cause bad feelings, but I am completely against the "what's best for the baby is all that matters" sentiment. This is happening in your body, through your body, and your body (as well as your opinion) definitely matters. Of course you would not do anything to jeopardize your child's well-being. Moms have the most at stake when considering their child's welfare. But I think that line of "what's best for the baby" has been used to bully moms into doing things they would not otherwise choose to do. There have even been (rare) cases of doctors filing suit against moms who were refusing a C-section that a doctor believed she needed. In several cases, the moms went into hiding, and delivered perfectly healthy babies naturally.
Medicine is not a science, and childbirth is really not a medical event. It's perfectly natural, and sometimes medical professionals forget that. My point is not that doctors are bad, but rather that they are not always right. Moms, when given good support and respect, make pretty damn good decisions about what is right for them and for their babies. I think that sometimes doctors get confused about what their role is. Medicine is a service profession, and coercion is not part of service. And, yes, I have been a medical professional for many years. I practice what I preach.
One thing you can do at this point is have an ultrasound to see if there are any medical conditions that would indicate a need for a sooner-rather-than-later birth. Might give you some peace of mind if you personally have any concerns about anything being wrong. But if you feel things are OK, and you feel it is in your best interests to avoid induction, then stick to your guns, mamacita!
If I were in your slippers, I would consult a doula or midwife for an opinion, as well as hearing your doctor's opinion. It could be really helpful (and validating) to hear from several experienced professionals. But just remember that all of these people work for you - their opinions certainly have merit, but you are the person giving birth. You have the ultimate responsibility to decide what is best both for you, and for your child. Don't get bullied into doing something that does not feel right to you by any professional.
Thanks for reading my long-winded post. Hope it was a help, and wishing you a beautiful birth,
V.
