alleycat1984:  my sister had gestational diabetes and they said her son was going to be overweight and predicted he was going to be over 8 lbs, but when he was born, he was only a little over 5 lbs.

I did not have GD but did have a baby that measured large (4 weeks ahead) and had to have scans every 4 weeks after my anatomy scan. He ended up being a pound smaller than they were estimating when he was born, and was a normal, healthy 7lb14oz.

As I was in labor, they did an ultrasound and said the baby is measuring 7+ lbs. He was 6 lbs, 3 oz when he came out 5 hours later.

I wouldn’t worry about estimated weights from ultrasounds.

I wouldn’t worry too much, their predictions aren’t always very accurate. I’ve heard a lot of women say the doctors overestimated birth weight.

alleycat1984:  I don’t know about GD, but I know that almost everyone I know has been told their baby was way bigger than it actually was in the end.  I wouldn’t worry about it too much.

My neighbour had gestational diabetes and her baby was still only 8lb 6oz which wasn’t abnormal considering she is 5’10. My mum didn’t have it and i was 9lb 8.5oz! Some babies are just big.

alleycat1984:  Ultrasound weights are accurate to something ridiculous like +/- 2 lbs!  That’s a huge range.  

My baby was measured at the 80th percentile at his 20 week ultrasound.  All the way along he’s been measuring larger than his gestational age, or larger than they’d expect based on where he was in his development. I was actually measuring behind until 25 weeks.  I went from being a week behind at 21 weeks to being 2 weeks ahead at 25 weeks.  I’ve stayed a head and I’ve been gaining a bit more ground (at 28 weeks I was measuring just shy of 31.)

I passed the GD diagnostic test with flying colours.  I skipped the screening test because my family has a strong history of high 9 to 10 lb babies and so does DH’s.  Given that GD wasn’t really tested for when most of these babies were born, there was some concern that it might be the reason for the large babies (I’m talkin 10 lb 1 oz and 10 lb 3 oz — those were my grandparents born around 1920. Huge babies for that time!)  

My mum is a twin, they were both 6 lb 5oz over 60 years ago, considered pretty big for twins at that time.  I was 9 lb 12 oz and my sister was 1 oz heavier, in the 80s.  My mum gained a grand total of 13 lbs with me (lost a bunch when she got sick just before I was born and ended up only being up 8 lbs at my birth) and less than 20 lbs (I think its 18 actually) with my sister.  So there weren’t any really massive gains there either.  Just big babies. 

Now, I will say, we are big people.  I am from a family where most of us are 6 foot or taller.

First of all, your baby is not ‘overweight’ he/she is just measuring ahead or big! Babies come in all sizes and ultrasounds can be inaccurate.

My baby has been measuring big my entire pregnancy (anywhere from 60th to 80th percentile) and I do not have gestational diabetes.

The growth estimates are primarily made on bone size so they do a pretty poor job of predicting weight.  The GD test should tell more.  At 37 weeks my daughter measured 7.5 lbs, on track for 9.5lbs when she was born at 41 weeks.  She was 6lbs 10oz.  She was super long and skinny.

alleycat1984:  I had GD and my baby was measuring two weeks ahead. They planned on inducing me a week early so that baby wouldn’t be too big. Baby actually had other ideas and came 7 weeks early!  I would assume they won’t allow you to go overdue if your baby is still big when the time cones.

Ultrasounds can be off by up to two or three pounds. I wouldn’t stress. Just do all you can to keep your blood sugar regulated and you will be ok and so will baby.

I didn’t have GD but my baby was always measuring big.  Ultrasounds indicated my baby would be around 6-7lbs but he was damn near 8.5lbs!

My baby measured huge for gestational age at every ultrasound. When they did the office gestational diabetes test it was negative, but they sent me in for the longer one anyway. It was still negative. Baby continued to grow (the ultrasound tech refused to guesstimate size, and said that once baby measured over 10 lb they would make no further predictions), and they took blood at every. single. office. visit. because they did not believe a baby could grow so large without me having gestational diabetes. I tested negative each and every time. A baby in the womb can be large (mine were proportionately long as well as heavy) and not be “overweight”. My DD was delivered via c-section at 38 weeks and was 11-1/2 lb. Her blood sugar was not abnormal, nor did I ever have gestational diabetes. While I am only 5′ 2″, my DH is 6′ 8″, so I blame him!
