The skull hardness and bone seam density of the 2-month-old baby are not fully developed; It can be corrected by changing the baby's sleeping position.

1. When the baby is one and a half years old, the front fontanel will be closed. After the front fontanelle of the baby is closed, the shape of the baby's head is fixed and difficult to change. When the baby grows up, the hardness of the skull will also increase and the seams will be closer, so the head shape will not change much. At this time, about 2 months. If the baby's head shape is found to be asymmetrical after 2 months, it is not too late to adjust it within 3 months. Parents need not worry too much. Babies over 3 months old have basically fixed heads and can sleep freely.

2. When the head is asleep, the mother needs to adjust the baby's sleeping position to the opposite direction in time. Generally speaking, the baby's head shape is set 4 months ago, from 1-2 months to the most critical stage of sleeping. If the baby has left migraine, try to let the baby sleep on the right side from now on; If your baby is right-handed, from now on, you should let your baby sleep on the left side as much as possible. You should also lie down properly and sleep opposite. This practice can save the baby's head as much as possible, but parents also need to let the baby lie down occasionally to avoid becoming sharp.

3. Change the position and talk to the baby. For the baby who loves to sleep on the right, the mother can generally talk to the baby on the left; If the baby likes to sleep to the left, the mother can let the baby sleep to the right, thus correcting the baby's sleeping position. Massage the baby's neck moderately, and the baby's head is asleep. Mother can correct it by massaging the baby's neck. If the baby's head is tilted to the left, massage the left neck, paying attention to the gentle movement. This neck massage method can relieve the baby's migraine symptoms.

4. Hold the baby's head with a towel. Mother can hold the baby's head with a towel on the side that loves deviation, so as to relieve the pressure on the baby's skull and correct the deformed skull. But this method needs the mother to watch, because the baby is easy to move when sleeping and the towel is easy to shift. Considering the use of the baby mattress, the biggest function of the baby mattress is to reduce the head deformation symptoms such as head deviation or flat head half a year ago and prevent the head deformation from further deepening. Baby mattresses should be moderately elastic, loose and breathable, which is more conducive to the correction of baby's head shape.
