I have a friend whose doctors said she was measuring 42 weeks at 37 weeks, so needed to be induced for huge baby. Ended in C-section of course, and baby was a whopping 6 lbs 8 oz.
: But in her case, it turned out to be a good mistake, as they'd totally missed the glaring signs of pre-e, and it finally ended up being diagnosed a week later when she was back in the hospital with heart problems.
On the small baby thing... If a baby is only 2 lbs 11 oz at 36 weeks, YES that baby probably needs to come out. There are cases where the baby can do better on the outside than on the inside, and that's a pretty obvious case to me. My son was a lb bigger than that at 29 weeks! If you leave an IUGR baby in too long, it could end up dying in the womb. On the outside, you can make sure it's getting the nutrients it needs. And no, IUGR is not just found in drug users or malnutritioned women. There are numerous things that could cause placental insuffiency. Obviously, that baby hadn't been getting enough nutrients for a long time. I believe that's the typical weight of a 29-30 weeker (my son was big for his gestational age).
