My daughter is only 3 weeks old, so I don't expect her to be sleeping through the night at this point, nor any point in the very near future, but I'd like to know how do you start sleep training and about what time do you start? I'd like to get a jump on it as soon as possible as I have to go back to work in a few weeks, and I'm not sure how I'm going to function if she's stuck on her current schedule. My girl was born entirely nocturnal. My husband and I have moved her to the living room and one of us just stays up with her in the living room so at least one of us can get some sleep in the bedroom. If we were both in the same room with her, neither of us would get any sleep at all. It's non-stop fussing all night long and feedings at least every hour. If I turn the lights off she screams bloody murder and won't stop until I turn the lights back on. It is currently 1am. She's been awake, flailing around and crying since 9pm and has eaten about 15oz of milk. I have changed 4 full, poopy diapers. This charade will continue until about 4am. Then she'll pass out and be hard to wake for feedings all day. How do I go about turning her schedule around?
