Whether a baby’s brain development is affected by frequent bumps on the head depends on the degree of the bump. Slight bumps will not affect brain development; however, more violent bumps may cause brain hemorrhage, concussion, etc., and in severe cases, may affect mental ability.
For minor bumps such as scalp abrasions, scalp hematomas, and minor concussions, the baby may have a mild headache, or nausea, or vomiting, most of which are reversible and generally do not affect brain development.
More violent collision may cause cerebral hemorrhage, subdural hematoma, skull base fracture, etc., the baby may have severe headache, projectile vomiting, serious consciousness disorder or even coma, at this time, the baby’s injuries are more serious, may affect the level of intellectual ability, or even leave sequelae or death.
Therefore, the baby’s frequent minor abrasions on the head will have little effect on the child and will not affect the brain development, but we should also try to avoid bumping to avoid serious trauma.
