Parents had better not give newborns to sleep on pillows, the reason for two main points, one is that the newborn’s neck is very short, if you sleep on the pillow, will make the head tilt forward or to the side, affecting its breathing or make it sleep uncomfortable, over time, may cause the newborn head and neck deformity. Second, the newborn’s head is relatively large, almost equal to shoulder width, flat sleep, side sleep are very natural, do not need a pillow. The baby can choose the right pillow after 3 months. The length of the pillow should be equal to its shoulder width or slightly wider, slightly longer than the width of the head, the height of about 5 cm. In addition, in addition to not letting the newborn pillow, but also pay attention: make sure that the baby sleeps on his back, not prone, not only can not lie on the pillow, but also can not put a soft towel and clothes under the head. When newborns sleep on their backs, the probability of sudden infant death syndrome (SIDS) is lower than when they sleep in a prone position. Side sleeping is also undesirable. The problem with side sleeping is that newborns tend to roll over into a prone sleeping position. However, prone is still a better sleeping position for premature infants with breathing problems and for infants with certain health problems, such as GERD.
