And she spake out with a loud voice, and said, Blessed art thou among women,
and blessed is the fruit of thy womb.
Luke 1:42 KJV

Ok, so you are expecting. You may be curious to know just how large the child growing within you has become at any given stage of pregnancy. Wouldn't it be handy if there was a scale based on familiar objects? Wouldn't it be fun if the sizes used could cover the entire gestation from the fertilized egg, also known as a zygote, all the way to his or her birth? I found just such a scale using seeds, fruits and vegetables of different sizes to illustrate the size of a developing fetus. For quick reference I will list the week of gestation followed by the "fruit" that approximates the size of your unborn child. A link will be supplied to the source for professional details beyond the scope of this "at a glance" version.
