Baby head shaping pillow for Flat Head prevention and Plagiocephaly correction pillow. Babies are born with soft heads to allow for the amazing brain growth during the first year of life. Because infants sleep for so many hours on their backs, their head can flatten in one spot. Placing babies in devices where they lie down often during the day (car seats, strollers, bouncy seats) adds to this problem. Cherish Baby Head Shaping Pillow is designed to provide infant head support and reduce baby flathead. The contour in the center relieves pressure to promote a natural round head shape. The anti-roll ergonomic design helps keep baby in the safest position; on their back. The material promotes ventilation to keep baby cool and comfortable. The pillow is sized to fit newborns on Day 1 and also fits bigger babies up to 12 months old.
