Adults say that children can't talk when they touch their skulls. Is it true?/You don't say.

This statement is wrong. Children have the difference between the front fontanel and the back fontanel. Generally speaking, the back fontanel can be closed in about three to four months, while the front fontanel can not be completely closed until the child is one and a half years old. At this time, the child's skull develops faster than the brain tissue.

Suggestion:

The space of brain tissue in the skull is still abundant, and it will be protected by cerebrospinal fluid, so even if it is pressed against the child's front fontanel, it will not affect the child, because the buffering effect of liquid will not cause any damage to the child's brain tissue, so this statement is wrong.
