is this normal for a newborn?

my baby has some loose skin (mainly her neck feet and hands, some on her chest too but not much) and it worries me a bit esp since she's skinny. she's 7 lbs but looks small (the newborn shirts they gave at the hospital are somewhat big on her), and she's not"chunky" or anything like I'm used to seeing on babies. her skin also is peeling, as shown below. I've been gently rubbing it to get rid of the skin, if not applying lotion to it every now and then. the peeling/dryness doesn't seem to irritate her at all, so that's a good thing. but the things I listed, are they normal? she's only almost a week old.
