Pillows for babies?

Aakanchie

Baby is 3 weeks old and I don’t use a head pillow for him as the doctors said no due to SIDS. But some parents use a head shaping pillow to avoid flatheads.

My son often turns his head towards right than left. I switch his sleeping direction each time he goes in the crib and turn his head when I notice it mostly on the right.

Advice? What are other stents doing? Yes or no pillow?
