Lily doesn't really talk much. She grunts, and says "Kitty Kitty". But we'd be hard pressed to say that she has actually called us "mama" or "dada".
I was in New Orleans with work for the better part of a week. My first morning back, Bobbie Jo brought Lily into our room. She set Lily in the bed, where Lily said "dada" and climbed over to me.
It was pretty sweet!
