Imaginary Sister

Amelia introduced me to Holly, her imaginary sister, today. Apparently Amelia and Holly are twins, because Holly is also two. Holly has long brown hair and black eyes and "looks like a princess". Amelia says Holly plays hopscotch and hide and seek with her. She spent a large part of the evening before bed wandering around the house looking for Holly's hiding spot, much to Charlie's annoyance -- "Who is Holly??"

I am thinking pretty soon we are going to need a bigger house for this imaginary friend menagerie...
