Inaccurate measurements???

So we went to the dr again today for a biophysical profile exam...basically another ultrasound measuring them again, the fluid, cord flow, etc. Just to show how much their measurements vary, today measured baby a at approximately 4 lbs 10-12 oz. And baby b at a whopping 6 lbs 8 oz! So I am very curious to see what their actual birth weight ends up being! However, this u/s tech seemed to get better angles and measurements then the one on Tuesday got, which now raises mor concern of the babies almost 2 lb weight difference. All the doctors are having a meeting tomorrow morning and will be reviewing my chart, in addition to calling the high risk obgyn to get his opinion again. My fingers are crossed that he will advise to move the induction date up earlier then next Friday. I really just think baby A will grow better out here with us! That is just my new "motherly instinct" kicking in!:-). I'm ready to meet our babies!!!
