When Elizabeth gets told no or she gets pulled out of something that she wants to be in, and pretty much whenever she doesn't get her way, sometimes she'll start crying and run over to me saying, "Baby sad!"
When she does this, we'll say, "Are you a happy baby?" and she'll make this funny face like she's pursing her lips and sucking air in while she composes herself. It is so funny! Then all of a sudden she's a smiling happy baby with wet cheeks. =)
Also, sometimes whens he is in a grumpy mood or upset about something, she will run back in to the room all of a sudden, with a huge smile on her face, saying "Baby HAPPY!" Yay! ♥
