Am I watching 'Alien' or my own tummy?!

Baby G can now be seen by the casual observer of my midsection.  Yes, you don't even have to put your hand on the bump to see Baby G move these days.  I noticed a little portion of my tummy pop out while I sat in a meeting today.  I thought surely I was seeing things - until Baby G did it again... and again... and again!  WOW!  I figured you wouldn't see it for a while longer - but apparently you do when your tummy's still rather small for the size of the baby!
