Newborns do not need to use pillows. Because the newborn’s spine is straight, lying flat when the back and back of the head in the same plane, and the newborn’s head with shoulder width is almost equal, flat sleep, side sleep are very natural, so newborns do not need to sleep with a pillow. But if the baby’s bed is relatively soft, or the baby wears thicker clothes, or after spilling milk, then the mother needs to pad a towel, folded into three folds under the baby’s shoulders, which helps open the baby’s airway, smooth breathing, especially for some babies with a short neck, or premature babies. General infants grow to 3-4 months, the spine neck segment appears forward cervical curvature, when the towel can be folded in half or folded into 1 cm high to the baby as a pillow. Grow to 7-8 months, because the baby began to learn to crawl, sit, the thoracic section of the spine appeared backward chest curve, shoulder development widened, it should be replaced with a 3-4 cm high pillow for the baby to sleep. Too high pillow can also be harmful to the baby, skeletal deformities, hunchback and other situations. In addition, the pillow should be diligently washed and changed, the baby’s head sweat more, often soaked pillow when sleeping, easy to make some pathogenic microorganisms and dust and other allergens adhere, easily lead to infectious diseases or induce bronchial asthma.
