Baby sleeps all day, up all night!

Erin
My daughter isn't sleeping much at night, it's strange..night comes and she just doesn't sleep, she sleeps throughout the whole day though. I read about day and night reversal, and they they will grow out of it, but how do you speed up the process? I hear you aren't suppose to wake them when they're sleeping (unless it's time to eat) and can't figure out how to keep an infant awake. Please help- Dying for sleep!
