Happy Baby

We brought Rilo into Adam's work the other day and boy was she being a ham.  She was smiling, laughing, waving and "talking" to everybody.  Someone asked if she was always this happy and I realized that I am pretty lucky, because yes, she is almost always this happy.  Now of course she has her sad moments, like yesterday evening for an hour where she was not content no matter what I did.  But for the most part, she is just a smiley, sweet little girl. 

Where does she find all of these binkies?
