thanks. what you provided clearly establishes that the crown to rump measurement is "not" the actual fetal measurement. by saying that the legs are "curled up and difficult to measure" acknowledges that they are not included in the measurement and therefore the crown to rump measurement at this stage is understood not to represent the actual fetal size.<quoted text>
Since you missed this when it was supplied to Ink, I'll supply it again for you.
"Note: Babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. After that, they are measured from head to heel. This is because a baby's legs are curled up against the torso during the first half of pregnancy and very hard to measure.
Weight: 10.6 ounces - 300 grams
(crown to rump) 6.5 inches - 16.5 cm
(crown to heel) 10 inches - 25.5 cm."
Being a hard-head doesn't work so well after your 20s. Get with it, man.
are you always so pig headed when it comes to admitting you are in err?
