Kome,
It is true that as baby gets bigger, the printout cannot accomodate the whole baby. I still remember I used to get printouts of just the head, arm, femur or abdomen. Then we will be staring that the printout trying to figure out what we are looking at! But at least for the printout my gynae provides, there is the weight, the abdominal circumference and the femur length on it. I think the last two parameters are for estimating baby's weight and EDD (this changes with measurements but don't have to follow lah. Just a gudge of the range of baby's weight, I suppose.)
janbebe,
4 printouts?! That is quite generous!
