Emotions Emotions

When Josie first came home a year ago, she was very solemn. She seemed very unsure of herself (with good reason) and didn't have very many expressions.
Over the past year however, Josie has become quite sure of herself and feels free to express a wide array of emotion. For example...

She questions what we tell her. She pouts when she doesn't get her way (which usually results in Andrew giving her her way!)
She observes her surroundings with great focus.
And she pouts some more (hey, she is a toddler). And our FAVORITE emotion that she freely displays...
JOY!!! Which is what she makes us express everyday.
All these emotions at 19 months?!? Makes me worry a little about the teenage years!
