Newborn baby, the spine is straight, the back and the back of the head are in the same plane when lying down, the neck and back muscles are naturally relaxed, and the head and the body are also in the same plane when lying on the side. If the pillow is high, it is easy to bend the neck. Some can also cause difficulty breathing, which affects normal growth and development. Therefore, newborns do not need a pillow. However, in order to prevent spitting milk, the upper body of the newborn can be properly raised if necessary.
The baby begins to learn to look up when she reaches 3 months, and the cervical spine begins to show a forward physiological curvature. The 6-month-old baby began to learn to sit, and the thoracic chest segment began to show a backward physiological curvature, and the shoulders also developed widening. If you do not use a pillow at this time, the head position is low, which will cause more blood in the brain than when using a pillow, which may affect the baby to fall asleep. Therefore, the baby should start using the pillow for 3 months.
The height and height of the baby pillow should be moderate, the length should be slightly larger than the shoulder width of the baby, the width is equal to the head length, the height is 3 to 4 cm, and can be gradually adjusted according to the baby's continuous development. The pillowcase is preferably made of soft white or light-colored cotton cloth. The texture of the pillow core should be soft, light, breathable, hygroscopic, moderately soft and hard, and can be filled with materials such as wick grass, buckwheat husk and pudding. Folk tea, mung bean skin, late silkworm sand, bamboo mushroom, chrysanthemum, papaya, etc. are filled with pillow core, but foam or acrylic or silk cotton should not be used as filler.
The baby's metabolism is strong, the head sweats more, it is easy to soak the pillow during sleep, and the sweat and dandruff are mixed. It is easy to make some pathogenic microorganisms and allergens such as mites and dust adhere to the pillow surface, which not only emits odor, but also is easy. Induces bronchial asthma or causes skin infections. Therefore, the baby's pillowcase and pillow core should be washed and aired frequently.
If your baby's pillow is too high or too low, it will affect the smooth breathing and blood circulation in the neck, affecting the quality of sleep and the mental state during the day. How high is the baby's pillow? This depends on the baby's age and physiological characteristics.
The baby in the month, the spine is basically straight, the head is relatively large, almost shoulder width, when lying down, the back of the head and the back are in the same plane, so there is no need to use pillows, you can also use adult towel to stack four Fold as a pillow. A baby with galactorrhea can not be solved by raising the pillow. He should be placed on the right side and the upper body should be raised higher. When the baby will look up in 3 months, the cervical spine of the spine will have a prominent frontal curvature; after 6 months of sitting, the thoracic segment of the spine will appear to the back of the chest; when it is 1 year old, the spine will appear to the front. The waist is bent, so after 3 months, the spine is no longer straight. At the same time, as the body develops, the shoulders gradually widen. At this time, in order to make the body position during sleep, you should start using the pillow. The height of the baby's pillow is about 4 cm, and for children it is 6-9 cm.
The baby's pillow hardness should also be suitable. It is easy to cause deformity such as flat head and face, and it will wear off a circle of hair in the pillow and appear bald. Parents often mistakenly believe that the baby is suffering from a sinus disease; too soft and large pillow will make the young age The baby is especially at risk of suffocation in the newborn. The pillow core is generally made of buckwheat husk or dried tea after soaking in tea. It is not only soft and hard, but also hygroscopic and breathable, and can be cleaned. Other items such as valerian seeds can also be used.
