What does it mean when my baby turns her head from side to side really quickly every time she rouses from her sleep? She's been doing this since birth and no, it's not because she's hungry and looking to latch. Could it be that her neck is itchy or she's feeling warm and trying to cool down?

How long does she turn her head side to side for 2-3 seconds, or 2.3 minutes? How old is baby now? Does she have irritated skin around her head or neck? If no, I would not worry, as a number of babies move their head left to right when they are tired. If she doesn't appear to be in distress then just observe, but no need to stress. it just maybe something she does to comfort herself.
