A. Safe materials: The pillow core is made of memory foam, and the surface is made of short plush. It is soft, breathable, and has good sweat absorption, making it comfortable to use. B. Scientific shaping: There are three sleep areas. The middle part has a hollow design, which helps with ventilation and sweat evaporation. It can help shape a healthy head shape, meet the various sleeping position needs of babies, and prevent flat heads. C. Washing instructions: Avoid washing it with water and exposing it to the sun. Simply wipe it gently and let it dry. D. Why a shaping pillow is needed: After a baby is born, the bones at the back of the head are not fully closed, and the baby spends much of the time sleeping. Also, a baby's skull is relatively soft and can be easily deformed by external forces, so a baby may need to use a shaping pillow. E.
