What is this sleep you speak of?

Scarlett, like many rock stars, is not down with the whole sleeping at night thing. She seems to think that nighttime starts at 3:00am. That's when she goes down easily and sleeps for three to four hour stretches. This lasts most of the day until about 10:00pm at which time Brandon and I would like to turn in for the night. Fat chance. Between about 10:00pm and 3:00am she's up to eat every two to three hours. Scarlett has also decided that at this time she does not want to sleep in her crib. She would much rather sleep on Mommy or Daddy. Sweet, but not so fun in the wee hours. I nap when she does in the morning, but it doesn't seem to make me less sleep deprived. My mom read to me from my baby book today, which said that at three weeks I was sleeping for five hour stretches and at five weeks I was sleeping for seven hours. So, I've been thinking - were babies sleepier in the 70's? Or is Scarlett a really a rock star?
