Good question. I say that, because when you an artist, there is no set bedtime. (especially when your work is in your home like me.) I will tell you this, it has been a long time since I went "to bed" between the hours of 12:30 and 1:00am like duffsmom have reported. Maybe after I adopt a baby that whole prospect will change. I have heard that mothers do not get any sleep until their child reaches the age of 18 years. Then, and only then will they worry if their child is warm or cool enough in college (if they go) or have enough money if that child works.
