congratulations on your new little one!
my first was jaundiced a bit after she was born (we have pictures of her getting ready to leave the hospital and she nearly matched her little pooh bear in color!). the doctors weren't worried about it at all though. they just said to put in front of a sunlit window for an hour a couple of times a day (we lived in an apartment and didn't have sunlit windows, so we sat with her in the car!
are you nursing? they told me that it was very normal for nursing babies to get a little jaundiced (can't remember why though). anyway, she cleared up within a matter of a few weeks and didn't have any problems from it at all!
my second used to just freak me out with her weird eye movements! seems they don't gain full control over their eye muscles for several months after birth. it's weird, but normal.
as far as the gasping noises, it's probably nothing, but keep an eye on it. she might just be experimenting with her body and the noises she can make... people might tell you she's too young for that, and maybe they're right, but i'd swear both my girls did similar things when they were just a few days old, and it really seemed like they were just experimenting with what they could do!
anyway, congrats again! how exciting to have a precious new baby girl!
