Help!

mY little angel god bless her.... is 7 weeks and likes to stay awake until 3 in the morning. This is not suprising since her father and I are night owls and work in the bar industry. However, I only work one night a week so the rest of the week I fight with her to get to her to go to sleep at a decent hour. She will go down around 8 and then take little cat naps until 3 and all she wants to do is eat. She will fall asleep on the breast or bottle and as soon as you set her down in bed she wakes back up. I have tried letting her cry for a little bit, I will give her the pacifier and she will spit it out within 10 minutes, it's like she knows it will put her to sleep. Moral of the story is that I go back to school in a month and can not function or get homework done with this still going on. Any suggestions would be helpful.
