It's supposed to, but I really don't put much stock in it. Especially since you've had 3 other children. I measured 7cm ahead with Seth from 20 weeks to 36 weeks when I promptly went to 10 cm ahead!!! He was 9.3, I had an anterior placenta and a TON of water. It depends on so many different things like baby's position, how you are carrying him/her, where the placenta is and how big it is, etc.<br>
Don't worry about it, seriously!
typically 2-4 weeks ahead for a repeat momma is very normal. even if you are more than that, there can be some normal reasons for that- everything from having a full bladder or being in a slightly odd position when you got measured to all the things the previous post mentioned. your midwife will be sure to let you know if there's anything that leads her to believe it might be something else you should be concerned about!
measurement of the uterus has little to do with how big baby is. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"> I have known women who measured 6+ cms ahead and came out with 7lbs babies and there was me that measured 2, 3 and 4 cms BEHIND and birthed a 9lbs 10oz baby.<br><br>
if you honestly want to *limit* the size of your baby then limit your intake of *fatty* foods in the last few weeks. also I would stop worrying about how big s/he is...I found that if a dr assumes a baby will be average/small generally the mother has little or no problems birthing them. we were all suprised when my ds was born so big and my dr assured me had we had a clue how big he was he would have scheduled a c-section! Just some food for thought. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">
I agree that there's really nothing we can do to "change" the size of our babies and uterus measurement is an awful thing to go off of. With my DD I measured behind throughout the whole pregnancy and she was almost 9 pounds. Also, who made the rule that you can't push out a "big" baby? I would find that offensive. There are no medical facts to back that up. I"m 5'3 and I've pushed out a 9lb. 6oz. boy with no problems or tears. If your doc is threatening C-sec based on what he or she thinks is a big baby then I would be looking for a new one.

AMEN AND DITTO TO THIS!!!!!
I know my midwife would have no problem with letting me have my VBAC even with a large baby, but I think I will feel more at ease if I knew the baby was not so large. I know it is impossible to tell & a lot is genetic. My midwife just recommended that I eat healthy & exercise so that even if it is a big baby, I will have the strength to deliver it. I had my ultrasound today & baby is right where he should be so hopefully he will stay that way. Thanks for the support.
Someone told me that big babies can be easier to deliver because fat is nice and squishy (their words not mine <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/mischievous.gif" style="border:0px solid;" title="mischief"> ) so they slide out better. I have no idea if this is true. But I can say that my 9lb 2oz girl was easier to push out than my 7lb 12 oz girl. She was my second, so that's part of it, probably. I know your body won't grow a baby too big for you to birth <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/thumb.gif" style="border:0px solid;" title="thumbs up">
Also, we can measure bigger or smaller depending on baby's position. My sister's baby was all cranked out long and stretching, but wasn't that huge, even though her measurements were high.<br><br>
Mine, otoh, for the first time in 4 pregnancies, are small (I think 21 or 22 cm for my 25 weeks), but still, I'm clearly growing a belly and baby is moving fine, etc... so I just think you have to take it all lightly. I wouldn't worry about any measurement difference of 5cm or less.
I always measure big. REALLY big. I'm measuring around 28 at 23-24 weeks. I've measured 45 at 39 weeks...usually about 5-7 cm ahead. My midwife says I have a big uterus <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/lol.gif" style="border:0px solid;" title="lol"> whatever that means!! I'm short, too, she said that can do it. I've never had a big baby, though- my biggest was 7lb 5 oz, then 7 lb, then 6 lb 12 oz. It's just an odd thing. I don't think it means much, really...I hope all goes well for you.
