I had an ultrasound yesterday (38 weeks, 3 days) to check the position of my baby because the midwife couldn't tell 100% if it was head-down. Luckily, it is, and the ultrasound tech said that, in her opinion, the baby looks like it's ready to go. Yay! I was relieved that the baby is in the right position, but she also estimated the baby's weight to be 8 lbs 12 oz. This is my first baby, so I know it's more likely to be overdue, and I'm getting very worried that it's going to be too big. I want to have a home birth, and I desperately do not want a cesarean.
How likely is it that the baby actually weighs as much as the tech estimated? My fundal height measurements are bang-on average, so I was surprised to hear that my baby might be so large. I do not have gestational diabetes. People are actually always commenting about how small my belly looks, but I think that's because I'm 5'8" tall, so my belly is probably taller and a bit less rounded than most.
That being said, my mother gave birth to my older brother on his due date, and he weighed 9 lbs 9oz, and I was born two weeks early weighing 8 lbs 10 oz, so there is a family history of largish babies. My mom is several inches shorter than me and gave birth to both of us vaginally, so I hope I'm also predisposed to be able to give birth to large babies vaginally.
Do I need to worry about losing my natural home birth? Is there anything I can *safely* do to prevent the baby from gaining too much more weight? (I doubt it.) I'm hoping that lots of sex with hubby and walking around will help bring the baby along sooner before it gets too gigantic.
Thanks for any advice or reassurance you can offer me!
The best estimates take into account HC (head circumference) AC (abdominal circumference) and FL (femur length) they measure each of those 3 times, average the measurements and the us machine combines the data to generate an estimate. Even then,the very best estimates are + or - 1lb.
Your midwife has a good idea of your pelvic dimensions and I'm sure is not at all concerned with you growing a healthy baby. We only think of 8+ as big because so very many babies are induced early. You will do great!!

Family history is a fairly decent indicator. My children have all been about the same size relative to their edd's. Which is pretty spot on with what my brother and I were.
Don't worry about size. I'm sure you've heard the stories of tiny women delivering 12 pound babies naturally. It's more in positioning. Having a homebirth as opposed to going to an intervention-happy hospital will really help your odds. You just need to trust your body to do what it's made to do and try not to worry. At this point, I don't think you can (or should) try to stop your baby from gaining. Obviously, eat the right kinds of foods, but big babies are good.
Walking is good for keeping you in shape and more prepared to give birth, just don't overdo it and make yourself tired and worn out. You baby knows when to come and your body knows what to do. Trust that.

As someone who had an 11lb babe and is now carrying a totally normal sized babe, I can tell you, for me at least, sugary treats are limited to 2 a week, carbs are kept to a minimum, my milk consumption is much lower than last time(I was downing two gallons a week easily...this time, maybe a quart a week), and even protein, that they push so much, is kept at a modest, but obviously increased, level.
But yea, the u/s can be off by 15% I've heard. They start pushing the c/s if the big babe seems like it might be diabetic, which GD babies are easily diagnosed by looking at ratios. Most GD babes aren't only big, but have extra large abdomens or torsos in comparison to the rest of their bodies. Its those kind of deliveries that make for a greater increase of shoulder dystocia (the scary term they tend to throw around for big babes), not necessarily just big babies, which many of us just tend to have.
Don't worry too much about it(I know, so much easier said than done )! Keep walking and keep taking care of yourself!
That being said, I understand the worry. At my 36 week appt, I was told that the baby was all of a sudden measuring 7 cm oversize and was sent for a longer glucose screen and an ultrasound. Luckily, the glucose test was totally fine and the ultrasound was showing the baby was 7 lbs 8 oz (this was at 37 weeks, 1 day) and everything was in proportion so all is fine (some people might worry about that size but since dd was 9 lbs, 1 oz and our family grows big babies, that size seems fairly reasonable and my o.b., who had seemed concerned up to that point, seemed to relax quite a bit). Is there extra fluid around the baby? A friend is measuring big and they think her baby will be big and she just had to have another g.t.t. because the extra fluid from her ultrasound supposedly indicates the possibility of diabetes.
Try not to worry (which I know is easier said than done). From what I hear, stress slows things down - give the baby a nice, relaxed environment and hopefully the baby will decide to arrive in a timely manner :-).
