I have no idea when it happened, but Reagan changed. She walks around the house making up stories and having conversations with me (and everyone else) like she's an adult. She talks ALL the time and never seems to lack for topics of conversation. Not only that, but she is so animated at the same time. She user her hands to talk now and tilts her head when she wants an answer. That giant leap that people talk about with their kids has officially happened to mine. :)
