2 week-old DD2 just won't settle in her crib at night at all. She'll sleep in her moses basket during the day quite happily, though. I've tried all the usual tricks (warming the mattress, swaddling, making a little nest out of a rolled-up blanket etc etc etc). We end up co-sleeping out of necessity but I don't want to, I don't get any sleep like that, and I'm not sure it's safe because DH and I are so extremely dopey now.
I'm averaging 2 hours sleep a night (not all in one chunk) and I just don't know how I can continue like this. I also have a 15 month-old DD1 and it's so unfair on her that I'm a permanently bf-ing zombie during the day.
Does all this settle on its own at the magic 6 week mark or is there something we could do to encourage DD2 to sleep in her crib? How do I survive the next 4 weeks? How much of an influence might bf-ing have, and could a night time bottle of formula help (I ff DD1 and don't remember the sleep issues being quite this bad in the early weeks)?
