"My Name is..."

Lanie has recently decided that she has a variety of other names and personalities depending on her mood.  Most often she has become 'Vivian,' and when we call her Lanie, she says, "I am not Lanie, I am Vivian."
One of the first times she did this was on Thanksgiving when she was sitting on the couch.  My father's cousin sat down next to her and said, "Hi Lanie, how are you today?"
Lanie responded, "I am not Lanie, I am Vivian."
"Oh," said Lucille, "I'm confused, isn't that Vivian?" and pointed to Vivian.
"No," Lanie replied, "that is not Vivian, I am Vivian."

At this point we just call her the name she is telling us she is.  We cycle through Vivian a lot, sometimes Victoria, Vivian's friend, at bedtime when she wants to be cuddled she becomes "baby Ellen," a baby she attends home daycare with.  The other night she was helping me do something, and she became "Mama," and I was "Lanie," which got very confusing.
Yesterday however, she was hopping around the kitchen in the morning while Chris was trying to get her ready to leave for the day, and he called her a bunny.  For the rest of the day, we had to call her "Little Bunny Foo-Foo."  I think we sang the song about thirty times yesterday.

Sadly yesterday ending with the kids finding a kind of creepy version of Little Bunny Foo-Foo on YouTube in which Little Bunny Foo-Foo cackles a little bit manically, so the night ended with Lanie chasing them through the house while they yelled, "Little Bunny Foo-Foo is evil!  She's going to get us!"
Which caused Lanie to get a light saber and run after them trying to hit them.
