My mother in law recently commented that S is happy in all of her pictures. I said that we just don't take pictures of her when she's upset!
In reality, she really is a happy kid. But she does have her moments. Case in point:
This was last night. She was tired, we think she's teething, and she was fighting sleep like a champ. But she never wins. She crashed shortly thereafter. The good news is, she woke up much happier this morning :)
