It won't make any difference. The plasticity of the baby's skull is very strong, and the skull has been shaping until the front fontanel is closed. A few days after birth, the deformation of the baby's head will gradually disappear and the head shape will gradually become round. Usually after two or three months, the baby's head can turn back to a relatively standard circle (but some parts of the baby's skull will be flattened). It's only a matter of time before the skull recovers naturally, so don't worry too much. It is best not to fix the baby's head by yourself. An inexperienced mother can easily hurt her baby.

Moreover, it is wrong to say that the head deformation of a natural baby will affect the intelligence. The baby's head will be a little deformed because of the extrusion of the birth canal, but the baby's brain development will not be affected by the shape change of the head at all.
