6 weeks and tilts her head

Alice
So my daughter is 6 weeks and I have noticed that she tilts her head to the right a lot. She rarely looks straight or to the left. She can if I move her head or does sometimes but not often. I will say, she sleeps in a swing and i do put her on her right side a lot so maybe those muscles are strong idk she has a dr apt tomorrow but what do yall think? Is this common? Anyone else go through this too?
