My understanding is that anything over 8lb13oz (or 4000g) is LGA. Was this based upon ultrasound or was this actual birthweight?? Are you talking about the baby's blood sugar??
My DD was estimated to be 9lb10oz (4300g) at a 40 week U/S and I was coerced into a scheduled c-section for it (by my CNM and the OB)
: SHe was born at 9lb8.5oz.
I also allowed them to draw blood to test her blood sugars. They were absolutely perfect (we nursed, nursed, nursed like crazy). I would refuse it (since it might give them a reason to try to force supplementation). Next time I will know better (about both the c-section, and the blood sugars).
Not a BP here, but your post caught my eye.
