What does she do when she is sitting up or laying down??
I don't think this sounds like any reason for concern, but babies can develop a condition called torticollis where the neck muscles on one side become tight, and they basically only look in one direction. this can have variations, and can be tough to spot sometimes.
to test for this, lay her on her back, and place a favorite toy on one side of her, see what she does, then repeat on the other. if she doesn't look to a certain side, or starts to fuss like it hurts, you may need to ask her ped.
my daughter had this, but we were able to "fix her" with just a week of therapy at home. good luck!!!
