I had monthly ultrasounds when my first was measuring large. At the last ultrasound they estimated him at around 9lbs but he was just shy of 11 lbs so ymmv!

I had a BPP say the baby was a full pound lighter than he actually was a few hours later when he came by urgent C section

I have a friend who was told her baby was huge and would die if she tried to have a vaginal birth and he came out in a couple pushes, I forget how much lighter than what the ultrasound said several pounds

The baby should be ballot-able and estimated to within a pound but physical exam skills went in the toilet with modern medicine

At 37 weeks I was measuring small (obviously due to the baby dropping, but ok) so they sent me for an ultrasound. They said baby was measuring 16th percentile and that I might be trending toward IUGR, maybe they would induce me in my 39th week, ugh.

I ended up going into labor a few days later and delivered at 38+4, baby was 40%+ for weight and like 30th for length. Absolutely not IUGR, baby wasn’t even small. Baby had just dropped because I was about to give birth!!

They do this so they can induce on their schedule, as opposed to having to go to the hospital on babies schedule. I knew this when they tried to indices for my "large" baby back in 2002, I told them no thank you, 8 lb 2 oz baby was not too large

Oh my, did they induce you based on the false measurement?

Same happened to me. They thought my DD was 14 pounds and had a huge head. She was born of normal size and weight. Yes, induced because they couldn't properly assess me.

After the baby's head is engaged fairly deep in the pelvis, since ultrasound can't see through bone, is it even possible for them to get accurate head measurements or images?
