Generally speaking, the appropriate height of the pillow is conducive to head blood circulation, to ensure a good sleep and promote growth and development. But for the newly born baby, is not suitable for sleeping pillows. The adult spine has four physiological curves, located in the neck, chest, waist, sacrum, and is not congenital, but slowly developed and formed later in life as the baby raises his head, sits, stands, and walks. The newborn’s spine is not curved, is straight, when lying down, the back and the back of the head naturally in the same plane, without the use of pillows. If a newborn is given a pillow that is too high, it will easily cause its neck to bend, leading to breathing difficulties and affecting normal growth and development. If the newborn is prone to spillage and vomiting, his entire upper body can be properly padded. When the baby grows to 4-5 months, the cervical vertebrae begin to appear forward physiological bending, then you can fold the towel to the baby as a pillow. When the child grows to 7-8 months, his thoracic vertebrae began to appear backward physiological bending, while its shoulders are gradually widened, then the child should sleep on a 3-4 cm thick pillow. In short, for the healthy development of babies, newborns and small infants do not need to sleep on pillows.
