My 3 year-old cousin talks in the bathroom alone!

I think that it's fairly normal. I have a three-year-old niece, who is learning to talk. Last saturday, I was out with her and her mother, my sister-in-law. My sister-in-law and I were having a conversation, and I could hear my niece talking, in the back. She seemed to be talking to herself. I think that it's really normal. I don't think that you should worry about your cousin.

I would not worry about it. She is probably just trying out her new sounds. I know some kids do not like to talk in front of other people till they can say words properly.

It is absolutely normal for a child that is learning how to talk to jibber jabber all over the place and you not understand any of it. It's their way of learning. Now the fact that she's looking up to the ceiling , maybe she does see something to focus on, but I really can't imagine it's ghosts.
