The baby's skull is still soft after three months. When sleeping, we can let him sleep on his back first, then sleep to the left, then sleep to the right and finally lie on his back. Sleeping on your back is also very beneficial to the development of the spine. Adjust the baby's sleeping posture every two hours. You can't always sleep in one position, so your head will be deformed.
In addition, it is good for the baby to eat cod liver oil and calcium tablets, eat some foods containing more calcium, such as milk and soybean milk, and get more sunshine, which is good for the development of bones.
