Congrats on the new bundle of joy!!!!!
My first thought.....Is she getting enough to eat? I say that because I had some b'feeding issues and my daughter was not getting enough to eat so anytime she wasn't eating she was crying.
if she was born on Wed, she's about a week old, right? So, is she back to her birth weight? I know they dip a bit right after they're born, but then gain it back.... I thought the rule was within the first week (but it's been a while since I had a newborn). does she have the appropriate # of wet diapers etc every day?
if you know she is getting enough to eat then this is probably behavioral.
Does she use a pacifier? Controversial, I know. But newborns have an instinctive need to suckle. So, if she's not eating, she may still need to suck and she can't soothe herself without sucking. A paci will fix this.
Can daddy do the middle of the night feeding with either pumped b'milk or formula? that will enable you to get a stretch of sleep.
Is there anyone you know willing to help you? someone from church, your next door neighbor, a mom from one of your other kids' schools? You could pick up from school, if she will come over one night a week and do the overnights etc.
Call your ped and let them know. No, not at 2am. Call now. In the middle of the day. She can probably give you some suggestions. And at least you are establishing a documented pattern of your daughters sleeping patterns. That is relevant info for your Dr to know.
My daughter went through a phase (probably a couple weeks older than yours, I think she was about a month old) where she just had to sleep while being held. it lasted about a week. So that's what we did. We took shifts. She sorta "grew" out of it. But man was it tough!!!! Hang in there mama.
