Ok, Audrey's night waking is really wearing me out.  This is really different that what Kate did so I am not sure how to handle it.  Here's what's up:

• About every 45 minutes to an hour, she starts to cry, but in a monotone, yelling kind of way, for about 5 minutes.
• Sleeping position does not seem to matter.
• She never truly wakes up, unless it's the daytime and there's stuff going on, or at 5:30ish for her first feeding.
• It's loud enough that it wakes us up every time.
• She doesn't usually need help settling down again, probably because she is really still asleep, but if she does wake up and get frantic her cries change.  She can be resettled easily with a pat and maybe the paci.
• She doesn't do it when sleeping in my bed with me, or on my chest for a nap, or in the car.
• She doesn't seem sleep deprived in the least - that's just me. She is super happy and eating well, and easy to put to bed.
• It's ALL STINKIN' NIGHT LONG.

I've heard of the "45-minute intruder" thing, where babies cry to change sleep cycles, and it is tempting to think that they are truly awake.  Some people equate that with not nursing enough, but she still nurses 7-8 times daily plus two cereal feedings, so SURELY that is not the problem.  Maybe this is a sleep-cycle related thing, but how do I deal with it?  I don't want to leave the monitor off entirely.  My first plan of action is to buy her a white noise machine, in hopes that it will help her sleep more deeply, or drown out the cries a little bit so I don't wake up so easily.

I just want to know if I am doing anything wrong, or if this is just a phase.  Any suggestions?
