Unsurprisingly, Rosie has been taking her job as a big sibling very seriously. We've been amazed with how patient and loving she is with Joseph. She impresses us with how calm she stays when he cries. In fact, she automatically goes into song to help calm him. In the beginning she would immediately break into a very high-pitched "I loooove you" tune. Since then lyrics have included "it's okaaay," "it's okay to feel sad," and, once, "if I could, I would marry you*." So sweet to see how much she loves Joseph and to see him start responded to her with big smiles.

* lyrics follows a conversation about how Rosie was going to live with Joseph forever because she was going to marry him. We had to break the news to her that that was not allowed.
