Hi, everyone, I know there is no scientific way to predict the baby's size before he is born but I am a bit anxious. HIs daddy is a big guy - 6.2 and 210 lbs and has a kid that was born at 10 lbs! He himself was 9 lbs... Can my doc tell what size my baby will be in advance? I am 32 weeks now and am measure at 33 centimeters.

Hi Hannah, I was worried about the same thing. My hubby weighed in at 11lbs. at birth and I weighed 8lbs. I am only 5'4" 125 (prepregnancy) so I am also terrified of trying to push out a whale! I asked my doc and he said I will probably have a 7 pounder. I have also heard that doctors are wrong a lot when predicting weight, they are only guessing! Good luck!

they are supposed to be able to do measurements on the ultrasounds and use some forumla to calculate weight. but I think it's a bunch of c___p. I've heard of so many doctors being wrong when doing this. from what I've read on my own, it's believed that a woman's baby size is directly related to her size and that in "MOST" cases a woman won't carry a baby larger than she can deliver. the operative word there, being "most".

Drs cannot really tell you. My SIL had an ultrasound at 38 weeks with her firstborn. She was immediately sent to a high risk doctor because the baby supposedly only weighed 4 pounds. Guess what a week later she delivered a 7 lb 3 oz baby. My cousin was induced due to a big baby. The baby was born at 6 lbs. They just don't really know. Its just a guess.

Hi Hannah! Just to ease your mind. I dont think there is any real way to predict size of baby, and while genetics can play a part......thats not all there is. My mother is 5'4", and was a small lady when she got pregnant with my sister and I. My sister (who was born first) weighed in at 7lbs 12oz. I came along as a whopper at 9lbs 4oz. My mom had a MUCH easier labor with me. she said I practically fell out of her, and my sister took hour or so of hard pushing. Size does not mean a more difficult labor. I also just had a friend who had a 9lb 1oz little girl. She did not have an epistiotomy, and had a fairly easy labor. On the flip side of things.... I have heard of women who had average to smaller babies, and had a heck of a time delivering the baby. do not worry............I'm sure everything will be fine.

A few weeks ago, someone on here (I think it was here) posted a website where you can predict your baby's birth weight by using a math equation. The article about it is at and it's called You can predict your newborn's weight. It's kind of a complicated equation but I tried it and it said my baby would weigh 8.5 pounds on my due date. It's worth a try! Just go to the site and search for the article. It's pretty interesting.

Neat webmd site. My baby will be about 8.5 lbs as well according to that. My first was 7 lbs 6 oz. and my second was 8 lbs 14 oz.
