Do you use a pillow for your baby? My baby is 8 weeks old and I only use a pillow on her when she is in view. Afraid to use it at night. When can she start using pillow?

Babies below one year of age do not need a pillow because of the risk of suffocation. You may want to do what others has suggested here if you want to elevate your baby's head a bit. Otherwise, there is no need to use pillow.
