My DD is 3 weeks old, and since she's not awake a lot...I think I mistake her awake-ness for hunger most of the time.
It just seems to me that if she's awake she must be hungry. A lot of the time when she's awake she will be moving her mouth like she's looking for something to suck on, but sometimes this is right after a "full meal." But sometimes even when she does this she doesn't respond by turning her head if I stroke her cheek.
Are there any more definitive signs that will let me know if she's hungry? Is it normal for a newborn to just look hungry and not really be hungry? Of course I worry she's not getting enough: any way to ease my fears?
