Question

How does a doctor weigh a baby while he's in the womb?

Answer 1

through ultrasound but sometimes they just feel it and they guestamate but that really isn't that accurate :)

Answer 2

They actually don't weigh the baby.

They take a complex system of measurements via ultrasound. They measure the circumfrence of the fetus's abdomen and head. They also measure femur length. I'm sure there are other measurements involved but unfortunately I don't know what they are.

Answer 3

it is just a estimation and is not always right

Answer 4

They don't actually weight them...  they estimate the weight based on the measurements they take during an ultrasound.

Answer 5

They measure your stomach & tell you an estimate of how big the baby is based on the month you are in & how big he/she should be.

Answer 6

its an estimate, even with an ultrasound its just a guess.  

Answer 7

I think its just estimates based on size of baby and what not.

I wouldn't pay too much attention to it if i were you though. they told me my first was 7lb13 then when he was born 2 weeks later he was 5lb 14.5.

Good luck.  

Answer 8

Answer 9
