Big baby? Anatomy follow up measurements

Question

I just had my follow up anatomy scan. I’m 25+3 , they said he’s measuring 2 lbs 1 oz, and in the 80th percentile. He was like 64 percentile at my 20 week US and only weighed 12 oz.
Said they measure fluid from 7-24 cm and I was 18.
They kept saying, “he’s measuring ahead” “big baby” and asking if I got my glucose level done yet.
Now I’m super worried that I’ll have gestational diabetes or like a 14 pound baby. I’ve only gained like 6-7 pounds and have really been trying not to overdo it on eating.
Are these fairly accurate? Anyone’s measurements totally off for previous babies?

Answer

Both places I have had my anatomy scans (2 different cities since we moved after baby 1) have told us it can be off by 1-2 pounds either way. With my 1st baby the scans kept saying she was ahead and at a follow up scan at 36 weeks was measured to be about 8 lb 2 oz at birth. She was born 6 lb 2 oz. My sisters last baby was approximated at 7 lb 5 oz and was born 8 lb 10 oz. Her other 2 kids were closer but baby 3 way off so yes they can be off as they obviously are estimated guesses based of pictures. If baby is super balled up or moves a ton during the ultrasound it can effect it. The doctor thinks that is why our 1st baby was off so much. She would always wrap up in a tiny ball during ultrasounds so they images weren't the greatest. Good luck and hope everything goes well the rest if the pregnancy!!

Answer

The measurements with my first were accurate, but I’ve seen many women say theirs were way off. My daughter measured a week ahead at 1 pound at her 20 week anatomy scan. By 36w5d she measured 2 weeks ahead at 7lb 12oz. She was born at 39w4d and weighed 9lb 7oz.

I had GD last time and they kept telling me he's huge he's going to be 10 pounds. I stuck to their diet and was good. Yah he was 7'7 and fine.  My guy though is a big and tall guy in the 95th% for everything.  If you have GD you have it and nothing you eat can make it go away.  I can't prevent it.

My son measured 9.2lbs at my 38 week ultrasound. My dr said it could be wrong and wouldn’t induce me or anything. I ended up going 3 days over my due date and he finally induced me. I gave birth to my son at 40+4 and he was 10.7lbs. So I would say sometimes they are accurate! But at that time a lot of people told me not to worry because their ultrasound measurements were way off. So I guess you never know.

I had gestational diabetes and my son weighed 5lbs 3 oz they kept saying he was going to be huge measuring ahead lol I guess they was wrong I thought he was going to be big as well because my stomach was huge I guess It was just all baby

Answer

That’s big, but not huge. Def get your sugars tested to be sure, but some people just have big babies.

Answer

At my 28 week appointment my baby was measuring 33 weeks. He was born at 39 weeks weighing 8 lb 12 oz. I’m not saying people love having babies that big, but it’s super normal! I wouldn’t overthink it too much. The last ultrasound we had a 38 weeks estimated his weight at 8 lb 10 oz, so my ultrasounds were very accurate.
