OK, maybe this is a dumb question, but I'm worried:

Our baby girl sleeps with her head to one side, so that she can see me in bed, I guess. She's 11 days old.

Her cot is by my side of the bed. It's an arms-reach co-sleeper cot and it's great so far - she's right by me but not in our bed, where she wouldn't fit and might get squashed or something. So she seems to mostly end up going to sleep looking in my direction and she stays that way. I guess she can't move her head enough to turn it to the other side yet, and she doesn't seem to stay balanced looking straight up - her head just goes to the side.

Is it normal, for a baby to sleep with their head on one side so they are looking over their shoulder? Will it harm her to sleep that way until she has the muscle strength to move her head about and support it more? How long until they can hold up their heads anyway?

It's worrying me because I know that I'd be uncomfy sleeping like that all the time. I'd get a sore neck. Maybe it's different for babies?
