Well, your little baby now weighs about six ounces.  He has fingernails and eyelashes.  He has his own unique fingerprint, which will remain the same until the day he dies.  His taste buds are now working and his hearing already developed at week 14.  There will be no more major developments.  Rapid Eye Movement (REM) is now detectable, a sign of dreaming.  Your spiritually adopted baby is already well-formed, both internally and externally.  He just needs time to grow and get stronger.  Quite a miracle, really.
