Night Owl or Morning Person?

Are you a night owl or a morning person or something in between? Do you know when this habit began in your life? Do you think people’s sleep patterns are really a part of who they are (like hair color) or can be changed with circumstances?

Before the triplets were born I was more of a morning person. I would go to sleep early and wake up early. Now, that they are here I tend to be a night owl. Once they are in bed that is when I can get things down around the house and my hobby so I tend to stay up late. I do take naps during the day when they nap though so this probably allows me to stay up late. I do not think that sleep patterns are what we are. I think it really goes by the circumstances of your daily activity.
