Baby girl fetus is 20 weeks along!

At 20 weeks, her digestive system is busy creating meconium (a tarry black substance made of swallowed amniotic fluid, digestive secretion and dead cells), which will fill the first diaper after birth.  I think I will leave that diaper for the hubs - I hear it really freaks out the guys!
By now, she is sucking in and out and practicing breathing.  All these motions are very important little helpers for after she's born when she has to start feeding.
