Curious or those of you not willing to induce, why, and would a big baby make you open to it?
I would not induce because it increases risks across the board for both mother and baby. The baby is going to come out on its own when it is ready so why not wait for that? Seems silly to mess with a natural process (barring medical complications of course) to save a few days or a week or so. There's a reason that labor starts when it does.
And no, a big baby would not change my mind unless there were additional medical complications to consider. Not only do they truly not know the size of the baby (it's just a guesstimate that can be off by several pounds), they definitely have no idea what your body is capable of safely birthing. Barring other medical complications it's rare for your body to grow a baby too large for you to safely birth. I would rather trust my body and the natural process of birth than accept unnecessary risks for me and my baby.
ETA: Also, keep in mind ACOG recommends against inducing based on baby's suspected size. If a doctor is encouraging it, they're going against evidence based practices.
I really would do some research on this topic so you can come to your own conclusions though. It's not as simple as picking out baby's birthday. If it was we'd all just induce at 39 or 40 weeks and be done with it.
