The femur -- the long bone in the upper leg -- measures around 2.8 to 3.8 centimeters in length. These estimates are based on standardized charts, such as the World Health Organization's fetal growth charts. The measurements of your fetus may be slightly smaller or larger.

You will see this in the first diaper change or two after birth. The fetus is also practicing breathing.
