First Baby Smile

This little lady brightens up my day.  For a while now she has been smiling with her eyes only - she opens them wide when she makes eye contact with us and they seem to sparkle.  Her mouth was a bit harder for her coordinate, but she finally figured it out last weekend.  It is fun to think that she is beginning to want to connect and communicate with us.  She regularly copies our facial expressions, moving her tongue and widening her eyes to match what we do. 

Her daddy calls her his little "toothless wonder"

What is it about a baby's smile that is so heart-warming and addictive?  It sweeps away every care in the world.
