First, the best time to sleep is to have a good head shape.
From the baby's birth to 1.5 years old, the skull will be in an unfused state for a long time, the fontanel has not been closed, the texture is soft, elastic and quite plastic, which is the golden age for adjusting the head shape; 1 year and a half later, the baby's anterior fontanel (there is a diamond-shaped gap at the top of the skull, with a size of 2.5cm×2.5cm, which feels pulsating) begins to close, the hardness and density of the skull become larger, the bone seams are tight, and the skull gradually solidifies. At this time, it is more difficult to intervene and correct the head shape artificially. Therefore, it is best for precious mothers to correct their baby's head shape in time, but it is not easy to correct it after 18 months (1.5 years old).
Second, how to sleep well
1. Because the baby's bones are not fully developed and soft, the weight of its head will exert pressure on the part of the skull that contacts the bed surface, causing this part of the skull to gradually sink, and finally a flat head will appear. Therefore, Mabao should adjust the baby's sleeping position in time, and it is best to do it on the back, left, right and prone alternately every 2~3 hours. In particular, long-term supine (easy to cause flat back) and lateral lying (asymmetric development on both sides of the head) should be adjusted in time.
2, the human spine has four bends-neck, chest, waist and sacrococcygeal, these four bends will gradually form with the growth of the baby, and when the baby is just born to 3 months, the spine is basically straight and has not yet formed a bend, so it is best not to use a pillow; About 3~5 months, the cervical vertebra begins to form the first bend. At this time, you can choose a relatively breathable and soft cotton pillow with a height of 1~2cm. At 6~8 months, the baby's thoracic vertebrae began to bend. At this time, you can put a pillow with a thickness of 3~4cm. All in all, treasure moms should adjust the height of the baby pillow in time according to the baby's physical development characteristics.
Third, how to correct the flat head
1, parents often massage the baby's neck, especially when the baby's head is tilted, it should be corrected in time. The correct way is: if the baby's head leans slightly to the left, massage the left neck, otherwise pressing the right neck will help relieve the pressure on its neck muscles and improve the head tilt to some extent.
The pictures are all from the internet, and the pictures have nothing to do with them.
2. When breastfeeding, be careful not to always feed at the same time and alternate left and right; When sleeping, you should also pay attention to changing positions with your baby frequently; When the baby is awake, parents can talk to the baby in a different posture.
3. If conditions permit, you can consider wearing a corrective helmet for treatment.
