Anyone Ever Been Told There Babys Arm/leg Bones Measured Small During an Ultra S

I had an ultra sound today to check my baby's weight. I have gestational diabetes so they do this since they can be larger at birth. Well I'm 34 weeks and she weighed in at 4lbs 7oz. BUT her leg and arm bones measured smaller then what they 'would like to see' at this stage of pregnancy. The doctor came in to look and said that she could just be petite and catch up after she's born, or there are sometimes complications and the baby could have some kind of 'syndrome' such as possibly being a 'little person.' It doesn't run in our families, but she said it is not genetic, it can just happen. I'm so worried. The doctor said there is no way to tell if she will be or not until she is actually born and they evaluate her. My mom and my husbands mom did say we have some smaller/petite people in our family history, and my mother in law is a very petite lady....so it could just be that, but the doctor said she wouldn't say anything if there wasn't SOME concern..they just don't know if it's a 'real concern' or not. I have another ultra sound in 3 weeks to see if they have grown. If yes, that's a good sign obviously, but I'm so worried. Has anyone else experienced this and if so, can you tell me your experience and what happend? I hope I'm worrying for nothing, but the hardest part is thinking I have to wait 6 more weeks until she is here to really know!

What can I do next?

My OB thought that with both of my pregnancies that my kids weren't gaining enough weight and that they were small ... my son was born 3 days before his due date and weighed 6 pounds 9 ounces and my daughter was born on her due date and weighed 7 pounds 6 ounces. Don't worry, everything will be just fine.

I agree with the rest of the posters. So many things could cause false readings in ultrasounds. No matter what ends up being the truth, you won't love her any less.. so enjoy your last few weeks, and keep in mind, the love of a parent for a child can overcome any obstacle.

I am 33 weeks pregnant. At my 28 week ultrasound my son measured very small (in the 10%). I've had two ultrasounds since then and now he's measuring within normal limits. Hopefully your child will catch up before your next visit.

I too had GD and had trouble gaining weight. I had a ton of ultrasounds (every other week for the last 3 months) and different ultrasound techs saw different things. He's small... he's big... his legs are short... his arms are long... he's not long enough... Ultimately, he came out a month early, just over 5 lbs and perfectly proportionated.

Hello -

I cannot give you advice specifically about short arm/leg bones, but I can tell you that 3d trimester ultrasounds are often very wrong about measurements which can be skewed for various reasons - abdominal fat (yours), the angle of the baby when they measure, shadows in the uterus and other factors. Even if the ultrasound tech places the calipers just a tad off it can cause a huge difference. You shouldn't torture yourself before she is born. My son (now 2) had "scalloping of the convexities" on 3d trimester ultrasound before he was born - basically he had sort of a *cone head* appearing head in utero. I had to get all sorts of testing to see what it was - nothing was definitive except they thought it would probably be OK. In any case, he was not a conehead when he was born, he is completely normal and it turned out to be nothing. Enjoy the last 6 weeks - and believe she will be a normal baby! L. W

I had high blood pressure during my first pregnancy. So like you I had lots of ultrasounds to check the babys health and growth. My baby girl always measured small. always 25% sometimes smaller. I was concerned and asked the dr... My dr. said "people come in all sizes and even the top and bottom 10% are normal.."

She was born at 6 15 on her due date. she grew very slowly.. and at one year was only 17 6 - which put her at the 5% for weight. by 15 months.. she was up to 18 8 - so she fell of the growth chart. she is so light that she isnt even on the chart.

She is perfectly healthy. she has had 1 cold and 1 stomach flu in her life. she has never been to the dr. becuase she was sick.

DONT WORRY... your baby is fine.. the only reason you know about this is the extra ultrasounds... If you were having a "normal- low risk" pregnancy- you would only have 1 ultrasound and you would not have all this scary info..

I am now pregant with my second child- a boy- I have only have th normal ultrasounds. and he is measuring average. so he will probably be a bit bigger than his puny sister..

S.,
My sister had the same thing happen to her. She was very very scared especially being so far away from home. It was the first grandchild in the family tooo. We also didn't have nothing like that run in our family. My nephew who is 9 now is a tall growing boy. He does have low weight but that is cause of meds that he takes for A.D.D otherwise he is a very healthy boy.

Now to the diabetes ... my best friend was diabetic prior to and post partem.... her son always "weighed in" veryyyy small... born THREE MONTHS early was barely a pound.... He just turned 16 in March and is almost 6' tall and close to 200 lbs....... Please dont worry... I know it is hard, but ultrasound is NOT 100% and even if it is she may just be an itty bitty thing for a min....
Good luck and let us know

S., I wish I could take away your worries, hopefully this will help. I also had g.d. and had a ton of ultrasounds due to the fact that I was 'old' ...35... and had a surgery to remove a septum in order to get pregnant. Anyways, yes, they thought our daughter was too little also, at first I gained very little weight - if not lost weight - each month. Then one month I gained 10 lbs and then very little after that. They did a very lengthly u.s. with a neurodevelopmental doctor measuring each and every body part on her. They were concerned about her size including tummy size, torso, arms and legs. This u.s. was so indepth that they measured how long her hair was.. .I clearly remember thinking 'hair? I am not worried about hair, this can measure hair?' The doc did say that she was smaller than she should be for the age. Now for the good news, she was born c-section 1 week prior to my due date (according to the docs). That morning of the scheduled c-section my water broke on it's own and I started to go into labor. She was ready to come on her own. They did do the c-section and they had her estimated at 6 lbs at the u.s. earlier that week. She was born at 8 lbs 1 oz. She did lose weight the first few weeks but it was not more than the % that they allow for newborns. She is now just very petite, she is only in the 5th percentile of weight and height but at least now she is on the charts at 18 months. She is starting to grow taller now and is filling out in her face. She is still only 20 lbs at 18 months, I was afraid she would be the only kid that technically should still be riding backwards in the car according to the car seat instructions but her doctors assure me that she is fine and perfectly healthy, just petite. If you want to chat feel free to email me, I hope some of this helps. Just remember to focus on your health at this time, stick to your g.d. diet - what ever your restrictions are and try to stay positive and calm. I do wish you the very best of luck and hope for a healthy delivery of your little princess - every family should have one :)

I would agree with the other posters. I had an ultrasound every four weeks due to high AFP levels; they induced me three weeks early because he was measuring small and the doctors were worried about his growth. At the last ultrasound, he "weighed" 4 lbs. 8 oz. He was born that day, and actually weighed 5 lbs. 3 oz. So, ultrasounds can be off. So try not to worry until there's something to worry about -- and you can deal with what is (a happy little baby!) when the time comes! Good luck and keep your spirits up!
