Our baby at 21 weeks

At 21 weeks, the baby is about the length of a carrot.

(For the first 20 weeks, when a baby's legs are curled up against the torso and hard to measure, measurements are taken from the top of the head to the baby's bottom — the "crown to rump" measurement. After 20 weeks, the baby is measured from head to toe. ~cited from babycenter.com)
