  • They usually determine it by how big you're getting and sometimes with the help of an ultrasound. They have some way of figuring if the baby is so big then he/she weighs so much. They're wrong a lot though.

  • I'm not entirely sure...and they can't be entirely accurate either. But they can use the dimensions of the baby's body measured against the known weight of such size of a fetus at that time to determine an estimated weight. I've never heard a of a doctor saying a specific weight for sure with no question.

  • This isn't a dumb question. Dr.'s don't know how much your baby weighs, at least I don't think so. I think its just an educated guess. My Dr. induced me at 38 weeks because I was miserable. She thought it would be fine because she figured the baby weighed about 6 1/2 -7 pounds. My baby was born 9lbs 3 oz. I am a small girl though and she was surprised that I had such a big baby. Thats why I think its just an educated guess-I don't know for sure though.

  • I think during a ultrasound, they measure the bones, head and abdomen curcumference etc. and somehow get an estimated weight.

  • i was going to ask that same question because i didn't understand it either, but thats cool that they can estimate it

  • The weight is an estimate based on sonogram measurements -- with both of my kids it was way off. They have no way of knowing how "dense" the baby is.. they go by averages based on the baby's stomach measurement, thigh bone, head size etc.

  • It is just an estimate and they are often wrong!

  • They can feel the baby through your stomach, and the ultrasounds give them a good idea too. Still, it is just a guess and they're usually a little off...but my doctor has been pretty close most guesses! (My friends and I all go to him). He is usually within half a pound.

  • They guess. They can only really tell how long the bones are, and maybe how chubby the baby is with a 3D.
    During labor, they said my first would be about 8 pounds (I had an ultrasound that day to make sure she wasn't breach). She only weighed 6 pounds!

  • My doctor said she doesnt say anymore. She told me "the baby will probably be between 5 and 10 lbs." Its almost impossible to know for sure.
