Here's a good example of the kind of stream-of-consciousness monologuing Sophia engages in most of her waking hours.
Sophia: Daddy, I want to wear my ugly dress today. It's in my closet hanging on a nail, just like my nail polish. My nail polish is over here. Daddy, look. See, my nail polish is melting off.
She'll often move across several different tenuous connections like that within the course of 20 seconds, and sometimes she even goes on for several minutes. We pick up very little of it most of the time because of how quickly she moves through the various stages.
She also likes to throw in lots of irrelevant information just because she likes to talk about it, so she'll tell me where her bear is (next to her blanket) and have to say that the blanket is a certain color or colors and that her Mommy made it for her. Sometimes she ties things to certain occasions or just mentions some term for a day a while back (often Saturday, which just means a while ago as far as she's concerned).
We got to see her cousin last week, who is only six weeks younger, and I was curious to see if she does the same thing. Not remotely, as far as I could tell.
Oh, and I have no idea why she calls it her ugly dress or why she nevertheless likes to wear it.
