Zoe is lovely and cuddly, and likes to be held upright next to my chest, which I really love as well. She's nestling there in a sling now as I type this; a sling that Bethany never took to, because she always liked to lie flat and sprawled out.
Bethany as a newborn had no concept of day and night; it was all the same to her. Zoe already has a very clear division into day and night - they're just the wrong way round from the rest of us. She's already in a fairly reliable routine, just not a convenient one. She has a very long sleep in the late morning, and sleeps quite a lot in the afternoon and evening, but she's awake pretty much solidly between midnight and 8am, and feeding nearly constantly, which is very tiring. The nights I've been alone in the hospital with her, which is the majority of the nights so far, that's been especially difficult because I've had to take care of her by myself all that time; whereas Wednesday night and last night were a bit better because Alex was there to help, and we had our bouncy crib, which is wonderful and allowed her (and us) to snooze briefly between feeds rather than going straight from one to the next.
She's quieter and easier than Bethany was during the daytime, and will lie happily looking at things or just cuddling. I don't know how much of that is a genuine personality difference and how much is just her being a bit lethargic from the jaundice - I don't want to enjoy that aspect if it's actually a consequence of her illness, but I think it's OK - I think Bethany was unusually active and demanding and probably most newborns are more like Zoe is.
She's already quite patient at waiting a minute or so for a feed while I faff about with pillows etc. She seems to intuit that milk is on the way, and wait contentedly. When she's not content, her cry is very high-pitched and actually relatively quiet, almost like a whistle, and it's only after a couple of minutes of that that she progresses to full-on yelling.
