Hair shedding in infants is very common and is usually caused by the friction of lying down and moving their head against bedding. Regarding washing, there is no one-size-fits-all rule; some parents wash daily for hygiene or cradle cap management, while others prefer 1-2 times a week to preserve natural oils. Always consult your pediatrician if you are concerned about scalp sensitivity or cradle cap, as they can recommend specific shampoos or washing schedules tailored to your baby's needs.
