Silk sheets for babys crib/sleep area. Silk reduces friction when they move so no hair pulling or scalp irritation from normal cotton sheets. The hair will grow back in its own time. All babys have this happen at one point. But i wouldnt suggest trying to use a product for any type or regrowth due to there skin being so sensitive.

Once at a store I saw they have these hats for babies with this little banana type of thing hanging from the top so when you place your baby to sleep you can place that banana on the left or right side so the baby rotates his head. I’m not sure how it works I never got the hat but it’s worth a try. You can probably find something like that on amazon.
