3rd Trimester

34 weeks pregnant and my baby already weighs 5lbs??

I just had my third trimester ultra sound and I can't believe how big my baby is already.  Is it normal for him to already weigh 5lbs?  Any mommies out there who have given birth to babies that weighed this much at only 34 weeks?  Or any information is appreciated.

  • At 32 weeks it was estimated that our LO weighed 4 lbs 12 oz.  U/S weights are just a prediction based on 3 measurements(length of femur and circumference of the head and belly) and can be off by 2+ lbs.

  • That actually sounds pretty normal to me, maybe a bit on the large side, but nothing to be concerned about.

  • At my 30 week my LO was estimated at almost 5 lbs., they kept saying I was going to have a 10 lb baby. He was 8 lbs when he was born. As the pp said they can be off by up to 2 lbs.

  • At my 35 week, this guy was measuring 6.5 lbs.

    I know it's just an estimate, but they also compared his measurements to DS1's at this point and he's measuring much larger.  (DS1 was 6lbs 15oz. when born at 40 weeks)

  • At 34w, mine measured 6.2 lbs. I think 5 lbs at 34w is pretty average. They didn't tell you the percentile?

  • My LO weighed 5.5lbs at 32 weeks. She must have had a growth spurt at that time because now they're guessing she'll be an 8lb baby which isn't too big at all.

  • it doesn't sound crazy, from now on the baby will gain abotu a half a pound a week, if you make it to 40 pounds the baby will be 8 lbs. nothing huge!
  • I'm 34 weeks today and my baby book says the average is for baby to be at around 5 lbs this week. Gaining .5 lbs/week from here on out.

  • My baby girl was 5lbs 3oz at 31w and is about 8lbs at 35 weeks =)

  • Sounds about right.  DD was born at 36 weeks and was 7 lbs even......DS was 8 lbs 7 oz at 37 weeks when he was born :)

  • I had a 32w growth ultrasound yesterday and she was estimated at 5lbs 3oz, I was told the estimate can be off by about 15%.

  • That sounds completely normal to me. I never had a 3rd trimester u/s so I don't know what my estimate was with DD. But "they" say baby gains 1/2 lb/week at the end. With 6 weeks left, that would be 3 lbs which would put baby at 8 lbs. Besides that, I've always heard 3rd tri u/s are very inaccurate for weight estimates.

  • I'm 38 weeks now, but at 35 weeks my estimate was 5lbs 1 oz and that was the 38th percentile.  I have a little girl and she's on the small size.  So no, I don't think that's big at all!  
  • At my 33 week ultrasound, she was estimated to weigh 4 pounds 9 ounces and the doctor said that was 40th percentile, so I would think 5 pounds at 34 weeks is pretty average.  My doctor is estimating 7 to 7.5 pounds at birth if she continues to grow at the same rate and stays put til 40 weeks.
  • At my 33 week ultrasound he was 4 pounds 9 oz and in the 75th percentile so that sounds about right. They guesstimated that he would be close to 8 pounds at delivery.
  • Thank you everybody for your reply's.  This puts me at ease and comfort to know I am right where IA am suppose to be.
  • Had my last ultrasound at 35w 5d and they said she was 7lbs 8oz.  They want to induce in two weeks because I could end up with a 10lb baby at full term otherwise.
  • My LO was weighing 4 lbs. 15 oz. at 33w4d and was in the 59th percentile.

  • At my 8 mo check up w/ DD my doc basically freaked that she was under 5 lbs and told me to eat anything and everything I wanted to fatten her up.  I ended up gaining 38 lbs total b/c I had already gained the 25-30 recommended for me.  So yes, I would say that's perfectly normal since 36 wks is "full term"/9 months (40 wks is really 10 months!)  She came out 6lbs 14 oz at 39 wks, which was fine, but still smaller than they wanted even though I never had any complications or concerns of any kind in my pregnancy- my doc this time around (we've moved since then) has said the same thing so I can only guess this is typical...
