I'm not sure how many of my friends are parents out there, but I have a couple of questions.

Is it normal for your children to stare and talk to themselves?

My daughter, Frannie, has developed a habbit of talking to herself, while staring at walls or at corners. It's as if she's actually talking to someone, but she never says who.

And my son, Franklyn. He's started doing this thing where he follows unseen things. One moment, he's playing and the next, he says he's following someone around.

I don't know if this is merely childhood imagination or something troublesom, but I was wondering if I could get a little advice.
